gbproxy/test: Test IMSI acquisition for RA UDP REQ

When a MS is state GMM_REGISTERED enters a new RA, it sends a RA
Update Request which is then handled by a gbproxy that possibly
doesn't have a matching tlli_info. In this case, depending on the
configuration an identification procedure to acquire the IMSI must be
started.

This adds tests to test_gbproxy_imsi_acquisition():
 - IMSI acquisition triggered by a RA Update Request message
 - Reaction to repeated RA Update Request messages, like it could be
   caused by packet loss between PCU and gbproxy.
