vf_ilpack: remove inline asm
This makes it multiple times slower. However, the output format (packed YUV) isn't handled efficiently by anything to begin with, and I have no clue we even have this filter. I guess it's one of these filters which find some use sometimes, but are not of higher importance, which justifies removing the faster inline asm.
