bts: f_init(): print testcasename() in the IUT's logs

It's useful to see testcase names in the IUT's logs in some
situations.  For instance, when some testcase crashes the IUT.

bsc: fix race condition in RSLEm

It may happen that the RSLEm component receives a DChan message
earlier than we suspend the DChan processing.  We saw this once:

  RSL for unknown Dchan
      BSC_Tests.ttcn:12769 BSC_Tests control part
      BSC_Tests.ttcn:5888 TC_ho_int_a5_4 testcase

Let's guard against this by calling f_rslem_suspend() earlier.

testenv: run "make deps" every time

The previous logic of not always running "make deps" was useful when
"make deps" would take a long time to complete even if there were no
changes. But this has been fixed in c7e40d6a ("Makefile: avoid fetching
deps if not needed"). Run it every time now in order to fix that deps
are not updated after deps/Makefile gets changed.

5gc: Initial NAS receiving support

With this patch it is already possible to receive the NAS Auth Request
in the test ConnHdlr.

nas.git dep needs updating to include a new patch fixing decoding of
NG_AUTHENTICATION_REQUEST.

5gc: Initial NAS transmitting support

With this patch it is already possible to transmit the NAS Auth Response
in the test ConnHdlr.
We still lack generating a proper RES to have the response properly
accepted.

testenv: podman: Install newer libcurl from bookworm-backports

It was already spotted a few days ago that libcurl4 7.88.1-10+deb12u12,
currently being shipped by debian12, contains some sort of bug where it
doesn't properly format/read HTTP2 requests when used in open5gs.
It was found out that installing a newer version of libcurl4 fixes the
problem.
This patch also fixes the problems spotted in the 5gc testsuite when
running within podman (they didn't show up outside podman because I'm
using Archlinux and hence using newer libcurl 8.13.0 too).

5gc: Fix upfd failing to start outside podman

tuns need to be recreated beforehand with sudo, as already done in
ttcn3-ggsn-tests-ogs, otherwise upfd would need root access to create
them.

testenv: use eclipse-titan 11 in Dockerfile

Install eclipse-titan from osmocom:nightly instead of osmocom:latest,
which now has version 11. Once we ensured everything works as expected,
we will upgrade the version in osmocom:latest too.
