compositor/blend.c: fix MT checker pattern

When filling the checker pattern from multiple threads, y_start
needs to be taken into account to determine the shade of the
current pixel.

Example pipeline:

gst-launch-1.0 videotestsrc ! video/x-raw, width=1920, height=1080, format=I420 ! \
  queue ! compositor sink_0::xpos=200 ! video/x-raw, format=I420 ! videoconvert ! \
