unix/variants/coverage: Add test for manifest freeze_mpy().

This uses the frozentest.mpy that is also used by ports/minimal.

Also fixes two bugs that these new tests picked up:
 - File extension matching in manifestfile.py.
 - Handling of freeze_mpy results in makemanifest.

This work was funded through GitHub Sponsors.
