Add Opus audio library and configure FFmpeg to use it

Opus support was enabled in 2ddfd51810e0. This commit adds the Opus
library and configures FFmpeg to be compiled with Opus support.

NOTE: It may be required to run `cmake -U '*FFMPEG_LIBRARIES*' .` in
your Blender build directory in order to refresh the `FFMPEG_LIBRARIES`
setting and add libopus.
