auto-t: add testOWE-transition

This adds several tests for OWE transition networks. Hostapd
does have special options for these networks but currently their
implementation is incorrect as the IE is not ever added to the
OWE BSS. Besides that using vendor_elements provides a much easier
way to create invalid IEs to test.
