video: Fix scaling in 4x horizontal co-sited chroma

4x downscaling of chroma with co-sited chroma has never worked
it seems.

Fixes incorrect videotestsrc output and videoconvert conversions
to Y41B, YUV9, YVU9 and IYU9 with co-sited chroma.

e.g.
gst-launch-1.0 videotestsrc ! video/x-raw,format=Y41B,width=1280,height=720 ! \
  videoconvert ! autovideosink
