Revert "ffmpeg: Add a -bare variant"

See:

I think this variant is probably not warranted unless we have some
concrete whole‐system numbers to justify the extra complexity in
dependency specification, especially considering that it will likely
lead to more copies of FFmpeg on many systems if used widely.

This reverts commit 9ad38b5.
