Bug 1879744 - Skip this test in tsan. r=aabh,profiler-reviewers

Bug 1915433 made this perma because it caused gfxPlatform initialization
(thus a bit more work), where before it used to be skipped by a pref.

But this happened intermittently before my patch, so likely this just
pushed the test over the limit...

Given the amount of tests skipped here on tsan, maybe we should have a
higher xpcshell timeout there?
