[PATCH] ddraw/tests: Only set DDSCAPS_OVERLAY if supported.

[Stefan Dösinger]

This patch is independent of 103075-103079.

VMWare apparently supports YUV formats as non-overlay formats (see
fg-win7u64* test machines). All the real hardware I have seen requires
DDSCAPS_OVERLAY for those formats.

There is no way to check format and surface type compatibility. If the
format is supported, but DDSCAPS_OVERLAY isn't, assume the driver
supports those formats without the overlay cap. If DDSCAPS_OVERLAY is
supported, use it for YUV formats.
