tests: Add testcase for (reassoc) roam failure due to auth timeout

Browse source 
Add testcase to verify failed roaming attempt due to authentication
timeout blacklists the correct AP. Roaming attempt is performed
with the reassociate command and bssid_set=1. Driver capabilities
are forced to non-SME and driver roaming (BSS selection) mode.
