[PATCH 2/5] d3d9/tests: Skip YUV tests if the formats cannot be converted.

[Stefan Dösinger]

The Windows 8 testbot supports some YUV formats as plain surfaces, but cannot
convert them to RGB in StretchRect. This check gracefully skips the tests.

The same limitation applies to my rather ancient Radeon 9000 Mobility.
