ports/96897: [PATCH] Add audio/py-mutagen

[Peter Johnson]

The xmms thing was a copy-and-paste error.  Sorry about that.  It may
be easiest to just remove the VORBIS knob; in order for the new
version of QuodLibet to support Vorbis, Vorbis must be enabled in this
port (although it's a knob on QL).  Are dependencies like that
typically handled through a -suffix port that explicitly enables the
knob?  Seems like overkill for a relatively small dependency.
