sound/sox: Reduce dependencies

Reduce dependencies and remove not used functionality linked in using external libs.

libsndfile: Unusual file formats
libpng: Only used to generate spectrograms
Clean up configure arguments
libid3tag doesn't fall into the BUILD_PATENTED category as far as I can tell.
