sgsn/test: Really parse received DL LLC messages
Currently just the number of intercepted downlink messages is counted
and eventually checked. The contents of the messages is lost. The
PTMSI contained in ATTACH/RAU Accept messages is just 'guessed' be
resetting the random number generator after reference PTMSIs have
been generated. While this works with rand_r, RAND_bytes cannot be
forced this way to recreate a certain number sequence (unless the
backend is replaced).
This commit changes this behaviour so that the last received msgb is
kept and decoded. The PTMSI that has been assigned by the SGSN is
then taken in the affected test cases and used instead of a 'guessed'
one. This is similar to how a real MS would react to the Accept
message.

sgsn/test: Add and call cleanup_test function
This (currently empty) function is meant to contain code that cleans
up the left-overs of the test functions. This will be needed by the
next commit that will store the last received msgb for later inspection.
