tests: Additional FST Setup test coverage
This adds a test case that goes through session initialization through separate commands that can be modified more easily for special case. The first such special case is using special FST Setup Request frames with non-standard MBIE contents to hit different code paths for finding the interface. Signed-off-by: Jouni Malinen <j@w1.fi>
