v4l2grab: Be sure that libv4l is properly converting to RGB24
From: Mauro Carvalho Chehab <mchehab@redhat.com>
To be simple, there's no format conversion inside v4l2grab. It relies
that libv4l will do the hard work of converting whatever input format
into RGB24.
Instead of just proceeding and writing wrong images, die if libv4l can't
convert into RGB24.
