Remove IWMMXT optimizations through libavcodec from libmpeg2.

According to Siarhei Siamashka libavcodec is faster on ARM so it is better to
use it directly instead of creating this hackish mix of two libraries.
Plus, these local changes would never be acceptable upstream, so no good
reason for keeping it in our local patchset remains.
