Explicitly enable/disable dependencies for sox

Explicitly enable or disable all optional features of the sox package,
as recommended in the "Guidelines for Creating Packages". This ensures
a consistent build result.

FFmpeg is removed because libsox doesn't build against its current API
anyway, whether told so or not; cf. http://bugs.debian.org/693642
