When the STA is forced to disconnect immediately after completion of
4-way handshake, there is a race condition on the AP side between the
reception of EAPOL-Key msg 4/4 and the following Deauthentication frame.
It is possible for the deauthentication notification to be processed
first since that message uses different path from kernel to user space.
If hostapd does not receive EAPOL-Key msg 4/4 prior to deauthentication,
no PMKSA cache entry is added. This race condition was making the test
cases expecting PMKSA caching to work to fail every now and then. Avoid
this issue by waiting for AP-STA-CONNECTED event from hostapd. This
makes sure the PMKSA cache entry gets added on the AP side.

There is no need to wait for the timeout if the ROAM command itself
failed. This could happen if an earlier test case had left hidden SSIDs
in the cfg80211 BSS table.

This verifies that hostapd uses Session-Timeout value from Access-Accept
as the lifetime for the PMKSA cache entries and expires entries both
while the station is disconnected and during an association.

The single channel scan while associated to another AP and immediately
after starting the second AP can miss the Probe Response frame
especially under heavy CPU load. Avoid false error reports by allowing
multiple scan rounds to be performed. wpas_ctrl_bssid_filter is also
modified to take into account different get_bss() behavior.

Only run-tests.py is actually executed, so there is no need to specify
the interpreter in all the helper files and test script files.
