X11 and Ozone: fix expectation in ClipboardTest/PlatformClipboardTest.TextTest

While fixing tests that started to fail with use_x11 && use_ozone
config, I encountered some additional expectations that were
not part of USE_X11 builds before.

And given that we are heading towards use_x11 && use_ozone build,
we need to continue to run tests and other stuff as it'd be
a single use_x11 build.

Also, it seems like our Ozone clipboard impl is more advanced
than non-Ozone/X11. Thus, disable this expectation for x11.
