glamor_copyarea: Don't access a DRM only pixmap.

Browse Source 
As EGL image/gbm only support ARGB8888 image, we don't support
other format. We may change the way to use gbm directly latter.
But now, we have to face this limitation, and thus if a client
create a 16bpp drawable, and call get texture from pixmap then
a copy to here may occur and thus we have to force retur a TRUE
without do nothing.
