Should we also be adding the same thing to "Linux ChromiumOS Tests (1)" and/or
"Linux ChromiumOS Tests (dbg)(1)"?

I added ash_mus_unittests to the same bots as mash_unittests. I suspect the bot
you mention is x11, which this test won't work with (and we don't care about
x11).

Hmm, presuming x11 and ozone are mutually exclusive, you're right that this
bot's config includes ozone and the others do not.
