virgl_renderer_transfer_write_iov doesn't work for YUV buffers, since
it's based on glTexSubImage.
We assume the YUV image is not disjoint, since that's currently what
Mesa gbm supports.
For RGBA buffers, this will also eliminate a copy in the cases
where the gbm_bo_map(..) implementation doesn't use a shadow buffer
[i915, mediatek, rockchip].

These formats can be allocated by gbm implementations.
v2: fix test (not needed on i965, maybe on softpipe)
