Revert of Use xvfb with Ozone CrOS. (patchset #2 id:20001 of https://codereview.chromium.org/2587473002/ )
Reason for revert:
Suspecting that this is causing intermittent bot crashes on after gl_unittests runs. See crbug.com/676128 for more details.
Original issue's description:
> Use xvfb with Ozone CrOS.
>
> We want to switch the majority of Ozone CrOS tests over to run with
> --ozone-platform=x11. This requires that test targets with type
> 'windowed_test_launcher' run using xvfb.
>
> Right now mb.py looks for the arg '--ozone-platform=x11' in the isolate
> step, which requires adding a new target for each test we want to add.
> Instead, just assume that if use_ozone=true and target_os="chromeos"
> then we want to use xvfb.
>
> Ozone CrOS test with type 'windowed_test_launcher' will still need to
> have '--ozone-platform=x11' flag added in chromimum.chromiumos.json to
> run with Ozone X11. Once most tests pass under with Ozone X11 the
> default Ozone platform can be swapped to be x11 and only tests that
> should run with headless will require an args entry there.
