[PATCH 3/5] tests: Add testcase for (reassoc) roam failure due to auth timeout

[Mikael Kanstrup]

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.
