gbproxy/test: Add a test with a P-TMSI collision between two SGSNs

This patch extends test_gbproxy_secondary_sgsn() by the establishment
of a third MS connection using a P-TMSI that has been assigned by the
other SGSN already. It is expected that the entries do not
interfere and are properly retrieved.

Note that these collisions are not handled properly yet.
