gbproxy/test: Add/modify test cases
Add a Attach Request message to test_gbproxy_ra_patching, where the
BSSGP RAI differs from the old RAI signalled in the LLC part. This
case had not been tested explicitely yet.
Change the RAI in the first Attach Request in
test_gbproxy_imsi_acquisition from rai_unknown to rai_bss.
Add Detach Requests to test_gbproxy_imsi_acquisition, one for a
incomplete attach procedure and one for an unknown (fresh) TLLI.
In these cases, the acquisition of a IMSI is not necessary and also
doesn't work properly with an E71.
