Subject: tvi_v4l2: let libv4l2 convert to a known pixel format

Signed-off-by: wm4 <wm4@nowhere>

Significant modifications over the original patch by not overriding
syscalls with macros ("#define open v4l2open") for fallback, but the
other way around ("#define v4l2open open"). As consequence, the calls
have to be replaced throughout the file.

Untested, although the original patch probably was tested.
