gbproxy/test: More TLLI expiry testing 

This patch adds a combined expiry test to remove one entry by list
length and another by age.

This patch also modifies the existing age based test to register both
TLLI with a different timestamp and to remove only one of the TLLI
entries by age based expiration.
