videoconvert-ffmpeg: fix passthrough mode

Browse source 
Keep the passthrough flag up to date when we unset a port format or when
it changes.

We should only fill in the buffer data/fd when the ALLOC flag is set.

We should only take the passthrough input buffer as output when we are
in passthrough mode.

Copy the header metadata.
