tests: assert pathname and flags when calling open()

Browse Source 
With this change the wrappers for mock and friends are able to take an
optional io_mock_fallback_open_state struct to assert expected pathnames
and flags whenever an open operation is called.

Based partially on https://review.coreboot.org/c/flashrom/+/62319/5
