Don't run the tiled-drawing tests on Lion WK2.

* platform/mac-wk2/TestExpectations:
Even though the platform/mac/tiled-drawing tests were skipped in the Lion TestExpectations
file, the Pass value in the mac-wk2 TestExpectations file was causing them to be run on
Lion WK2. Explicity skip the tests on Lion here as well.
