Switch mash_browser_tests back to Ozone headless.

Switch mash_browser_tests back to Ozone headless.

The test has been flakey for the last few days. Switch back to Ozone
headless to see if it helps.

The test also runs on an FYI trybot. Change it so that test continues to
run Ozone X11 but it will now use osmesa instead of EGL. This will give
some indication of if it's Ozone X11 in general, something to do with
Ozone X11 EGL or unrelated.
