ffmpeg: disable altivec on ppc by default

Since 4.3 ffmpeg uses vsx-specific instructions, which aren't
available on older ppc machines (including qemuppc):
https://github.com/FFmpeg/FFmpeg/commit/3a557c5d88b7b15b5954ba2743febb055549b536

This disables using the instructions with an option to re-enable them
for vsx-capable targets.
