Add support for META_OUTPUT buffer type to v4l2-ctl.
Signed-off-by: Sakari Ailus <[email protected]>

I've reworked the patch to match with the way SDR is implemented: the
options for setting the format work independently of the node type.
I like this better than the previous one; there is much less redundant
code now.
