library/ngap: do not link against libfftranscode

TITAN has built-in ASN.1 PER codec since version 10.0.0.
We're already using it for NGAP, so libfftranscode is no longer needed.

testenv: do not install/check-for libfftranscode

All testsuites have been migrated to TITAN's own ASN.1 PER codec,
so installing libfftranscode is no longer required.

5gc: Introduce tests for emergency services

These tests are expected to fail since open5gs has no specific logic for
emergency services in open5gs-amfd, and announces no Emergency Support
in Registration Accept.

s1gw: fix TC_uemux_e_rab_release_ind: pass release_ind := true

TC_uemux_e_rab_release_ind never actually tests the release indication
because release_ind is false instead of true.  The test body becomes
identical to TC_uemux_e_rab_setup - no release indication is ever sent.

s1gw: fix TC_e_rab_setup_failure: expect a specific S1AP PDU

setup_rsp is carefully constructed, but is not actually used.
The f_ConnHdlr_rx_s1ap_from_enb() call falls through to the ? default,
so the test accepts any S1AP PDU and never validates that the S1GW
actually populated the failed-items list correctly.

s1gw: f_ConnHdlr_conn_track_disable(): set conn_track := null

After deactivate, conn_track still holds the now-dead reference.
A second call (which can happen if any test explicitly calls this
before f_ConnHdlr_s1ap_disconnect()) will attempt to deactivate an
already-inactive default, which is a TTCN-3 runtime error.

s1gw: S1GW_UEMux.f_trx_s1ap_pdu(): fix setverdict() message param

On timeout pdu was never assigned (it's an out parameter), so TITAN
logs <unbound>.  The useful diagnostic is the expected template,
not the received value.

s1gw: remove unused mp_s1gw_mme_ip

We don't really care what address the S1GW is using when connecting
to our virtual MME.  This is why this parameter is not used anywhere.
