tests: Make PASN checks for PTKSA_CACHE_LIST a bit more robust

Browse source 
It was apparently possible for the test script to fetch the
PTKSA_CACHE_LIST information from hostapd before the PASN message 3 had
been processed since only the event from wpa_supplicant related to
sending of that frame was explicitly waited for. Add a small wait to try
to avoid this race condition with UML time-travel.
