cros: Clean up mash early-exits in ash_unittests --mash

Our policy for mash is to disable via filter file unless the test is
never expected to work under mash.

Also re-enable a bunch of tests that now pass under mash, likely due to
the display manager work done several months ago.

Is this still an issue after the WS2 conversion?

We no longer have separate display management, so there isn't anything special to do here.
