sgsn: Introduce test TC_attach_req_id_req_ra_update
The scenario in this test triggers a crash in osmo-sgsn fixed by
osmo-sgsn.git I64fa5cf1b427d3abb99e553e584897261a827ce6.
With that osmo-sgsn patch applied, the process doesn't crash anymore but
the test still fails due to an XID message being sent with a new
yet-not-seen-by-ttcn3 TLLI and as a result TTCN3 BSSGP_Emulation fails:
BSSGP_Emulation.ttcn:390 setverdict(fail): none -> fail reason: "Couldn't find Component for TLLI 'FE791757'O", new component reason: "Couldn't find Component for TLLI 'FE791757'O"
Other than that, the test runs fine. It still needs to be clarified
whether the new TLLI sent by osmo-sgsn is expected and test needs to be
fixed, or whether it's an sgsn bug.
