eim/testenv: put mnesia database into volatile location

When running the TTCN3 testsuite in testenv, we create the database
files in a non-volatile location. This means that with every
consecutive test run, the database from the first test run is
re-used. This may lead to unexpected behaviour.

With this patch we change the location of the database to a volatile
location, so that each testrun uses a fresh database.

stp: tcap: Avoid need of N_NOTICE.req

Commits
7970ceaead78ff224390a25f416b22bcd8e4e37e..32618160bdb154ca756c783b67b131533226f7ae
added a fork of titan.Protocol.Emulations.SCCP with a new N-NOTICE.req
primitive which was needed in STP_Tests_TCAP to trigger transmission of
a UDTS message.
That primitive doesn't exist in the specs, since no user of SCCP is
expected to be requesting a transmision of UDTS.
Hence, this commit rewrites the test to avoid the need for such a
primitive, by hooking directly into the lower layer MTP3 User SAP (M3UA
or IPA) and crafting and transmitting the SCCP UDTS over there directly.
Follow up commits will revert the commits adding such a N-NOTICE req to
the SCCP and TCAP layers.

related features. Since it will be used in more places in follow-up

deps: Update nas.git to rebased branch on top of v1.2.1

We have a forked repo of ETSI's nas.git on our osmocom gitea, which
contains an extra fix for upstream (currently waiting to be merged [1])
and one patch implementing C++ helpers to fit our own environment, which
needs to be kept downstream.

There has been quite a lot of development in upstream lately (TTF_T059),
with eg. old NGAP.git code being put inside nas.git (we are still using
our own copy of NGAP inside osmo-ttcn3-hacks/library/, but that may
change in the future).

A new branch rebased on top of upstream's master (v1.2.1) has been
pushed to our forked repo, so use it here to already align better with
upstream, easing further work and contributions in the future.

testenv: Dockerfile: rebar3 version via apt-cache

When building for Debian Unstable, we need a higher rebar3 version so it
is compatible with the Erlang OTP version in the distribution. Get the
version of rebar3 from the distribution via apt-cache and download it
instead of hardcoding a version number.

CCID: Check if reader times out while expecting procedure byte

A case 2 APDU (according to ISO 7816) is sent toward the reader. The
reader expects a procedure byte or a status word. If none of these are
sent by the SIM the reader must timeout and send an error message back
to the host.

CCID: Check if reader handles Abort correctly

The tests aborts an ongoing case 2 APDU (according to ISO 7816). The
SIM responds with a NULL procedure byte so that the reader does not
time out.

The abort messages are sent on both, the control pipe and the bulk
pipe with the same sequence number.

This test fails with osmo-ccid-firmware, because the abort
message/handling is not yet implemented.

A case 2 request (according to ISO 7816) is sent and a response with

procedure byte, nor a valid status byte.

This text expects the reader to return an error that states an incorrect
received procedure byte.

STP_Tests_TCAP: Fix ipa_to_ipa testcase

tcap routing doesn't work the way the test thinks. E.g. a Begin can't be
routed to a special destination because it does't contain a dtid which
is needed to route to the correct ASP.

bts: TC_pcu_interf_ind: check reporting interval instead of absolute FN

Recent osmo-bts commit 53f0ec29 broke TC_pcu_interf_ind:

  Verdict: fail reason: Odd TDMA frame number := 935

There's no requirement that periodic interference reports must land
on a TDMA frame number satisfying 'fn mod 104 == 0' - only that they
keep arriving every configured averaging period.  Instead, verify
that the interval between consecutive reports equals 104 TDMA frames
(1 SACCH period), using the new f_gsm_fn_sub() helper.
