Evas GL masking: Skip fast path if colorspace is not supported 

Masking in GL assumes only one texture to sample from. This means
RGB+Alpha and YUV types are not supported. While it would
make sense for RGB+Alpha, it doesn't make any sense for YUV (because
masks are alpha planes and YUV is opaque...)
