codecparsers: vc1: fix bitplanes decoding (DIFF6 or NORM6).

Browse source 
Fix decoding of DIFF6 or NORM6 bitplanes with an odd number of lines
(3x2 "horizontal" tiles). In this case, we have to skip the first line
of macroblocks but <width> number of bytes was used to do so, instead
of the actual <stride> size.

This fixes decoding for the video sample attached to:
