Disable Direct2D checks failing under Wine

Now that these Direct2D tests are compiled, disable those of them that
fail under Wine due to missing support for Direct2D functionality we use
in Wine implementation.

Don't even give a warning message because there would be too many of
them in these tests, just skip them silently.
