video: fix some vo_direct3d crashes due to FFmpeg nonsense

For incomprehensible reasons, AV_PIX_FMT_GRAY8 (and some others) have a
palette. This literally makes no sense and this issue has bitten us
before, but it is how it is.

This also caused a crash with vo_direct3d: this mapped a texture as
IMGFMT_Y8 (i.e. AV_PIX_FMT_GRAY8), and when copying this, it tried to
copy the non-existent palette.

Fixes #1113.
