This seems to work now.

The following revision refers to this bug:

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.
