mp_image: hack to fix alignment for certain image formats

Browse Source 
This is to get rid of swscale alignment warnings with the new OSD code.
Only image formats used by it are fixed.

Solving this generally would require some more effort. (Possibly by
using libav's allocation functions plus lots of testing.)
