Bug 1602980 - revert to having distinct skiaContent and gtkWidget annotations for transformations-1.html r=gbrown

Changes:

Partially revert the changes made in D56572 because it appears reftests running on macosx1014 also rely on the `skiaContent` manifest.

The unified manifest condition caused the `macosx1014-shippable-qr` tasks to report a failure with `1-1,1-1`. A separate bug should be used to update the expected failure values for macosx1014 if appropriate.
