My current nouveau_video_buffer_create calls vl_video_buffer_create_ex
with an extra flag set to indicate I want a linear resource. If no capable
hardware is found normal resources are used instead. Since I added a
fallback to g3dvl, it made sense to me that I just added an extra flag
during creation instead of copy pasting the video buffer implementation.

The only thing different between vl_video_buffer and
nouveau_video_buffer_create is that the latter sets
NOUVEAU_RESOURCE_FLAG_LINEAR, rest can be identical.
