[Buildroot] [PATCH v2 3/4] package/mpd: introduce id3tag feature dependency

[Andreas Ziegler]

id3tag is a sub-feature that is needed to extract information from mp3 files.
It selects the corresponding library and handles config settings. Two other
features need this sub-feature, but handle all library selections themselves
and omit enabling the id3tag feature. In consequence, users have to remember
to select both mp3 library and id3tag, otherwise the mpd executable will not
process mp3 files.

Reflect feature dependency in mpd Config.in to make id3tag selection automatic.
