Unreviewed, test expectations update.

        Added pixel expectations for compositing/ layout tests on
        chromium-gpu-linux platform and updated
        chromium-gpu/test_expectations.txt with needed SKIP entries for
        currently failing tests. The majority of the text tests pass by falling
        back to the Windows test expectations.
