ffmpeg patches

[Taylan Ulrich Bayırlı/Kammer]

These are fairly trivial but:

- Please verify the commit message style.

- The second adds a (gnu packages audio) import to (gnu packages video),
  which makes sense I think because video media usually contains audio,
  but in my Audacity patch I had added (gnu packages video) to (gnu
  packages audio) because Audacity uses FFmpeg, and that would be a
  circular import.  I would say Audacity should go into its own module,
  and we will have to remember that we cannot import video from audio.

Subject: [PATCH 1/3] gnu: ffmpeg: Fix comment.

* gnu/packages/video.scm (ffmpeg): Remove libmp3lame from the comments listing
  additional optional dependencies, because it's already been added on the
  meanwhile.
