Reland "ozone/x11: enable chromium_linux_gtests."

This is a reland of cfa5c0a4f35dd3c438a1c0561e182852bcd60cf2

The problem was that the filters were applied to the CQ tester
instead of the CI tester. That resulted in many fails in the CI
tester and the patch was reverted.

Fix: apply filter to the correct tester.

Original change's description:
> ozone/x11: enable chromium_linux_gtests.
>
> This CL enables chromium_linux_gtests for Ozone/X11.
>
> I wanted to add test suites step by step, but it seems like
> it doesn't make sense to do so for Ozone/X11 as almost all
> the tests pass except SkiaVulkan test in cc_unittests and
> a couple of tests in ui_base_unittests (crbugs created).
>
> Also, vr tests are not enabled as for some reason the
> bot complains about not found $DISPLAY for X11.
> This will be investiaged.
>
> Wayland tests will be enabled separately as they require more
> work.
