Add some tests to the CrOS device bot on fyi.

Adds one Gtest (base_unittests), the sanity test, and all chrome tast tests.

Will add them to this bot:
https://luci-milo.appspot.com/p/chromium/builders/luci.chromium.ci/chromeos-kevin-rel-hw-tests

Theoretically this should work now that crrev.com/c/1380332 has landed.
Only one way to find out though.
