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.
