After some code changes the FT-FILS AKM was no longer selectable
inside network_can_connect_bss. This normally shouldn't matter
since station ends up selecting the AKM explicitly, including
passing the fils_hint, but since the autotests only included
FT-FILS AKMs this caused the transition to fail with no available
BSS's.
To fix this the standard 8021x AKM was added to the hostapd
configs. This allows these BSS's to be selected when attempting
to roam, but since FT-FILS is the only other AKM it will be used
for the actual transition.
