tests: Add a unit test for mok mirroring

Test that our mok mirroring doesn't ever try to delete any variable that
it has previously created, and that it properly mirrors at least
MokList, MokListX, and SbatLevel, at least when variables actually work.

These tests will fail (rather a lot) without 7f64fd6da9458b73c4.

Currently valgrind shows a memory leak in this code which is not
introduced in this patch series.  Since all of our memory is freed on
Exit() or when kernel does ExitBootServices(), this doesn't have any
significant repercussions.
