vp9: fix crash if segmentation=1, keyframe/intraonly=1 and updatemap=0.

The reference map is never used in such cases, but we accidently copied
it anyway. This could cause crashes if this map has not yet been
allocated. Fixes trac ticket 3188.

avformat/mov: Do not compute a grayscale palette for cinepak in mov.

This was never done for avi files, the decoder always produced
output no matter if a palette was computed or not.
Since a non-standard palette was needed, this simplifies the code.
See issue 1067 and ticket #165.
