lavfi/super2xsai: fix table used to update color matrix at the end of each y loop

Browse Source 
The previous table appears to be wrong (it was copied from the original
MPlayer super2xsai filter in order to keep binary compatibility).

The new table is consistent with the init code and apparently fixes a
combing artifact on the left edge of the generated image.
