tests: Association comeback mechanism in wpa_supplicant

Browse source 
Allow the Timeout Interval Type field in the Timeout Interval element to
be overridden with a different value for testing purposes to be able to
bypass the association comeback processing in mac80211. This allows the
wpa_supplicant internal functionality to be tested.
