tests: WDS 4addr behavior on reassociation and with open and WEP

Browse source 
This extends the ap_wds_sta test case to cover post-reassociation case
(both with and without Authentication frame exchange) and add similar
test cases to cover open and WEP cases in addition to this existing
WPA2-PSK test case.

These cover functionality testing for the previous fix in
reassociation-without-new-authentication case. In addition, these find a
new mac80211 issue for the WEP + 4addr combination.
