[media] vivid: fix test pattern movement for V4L2_FIELD_ALTERNATE
The successive TOP/BOTTOM fields did not move as they should: only
every other field actually changed position.
The cause was that the tpg needs to know if it is dealing with a
FIELD_ALTERNATE case since that requires slightly different handling.
So tell the TPG whether or not the field setting is for the ALTERNATE
case or not.
