tests: Interworking auto_interworking=1 with mismatching BSS

Browse source 
This is a regression test case to detect a failure that resulted in an
up to five second busy loop through wpa_supplicant_fast_associate() when
interworking_find_network_match() and wpa_supplicant_select_bss() get
different matching results.
