Carlos Rafael Giani b17fe4aba4 meson: Make SDL2 and libsndfile dependencies configurable 
This is important for cross-platform build frameworks such as Yocto
where the build configurations must be deterministic. In this case, if
some other build dependency pulled in SDL2, then the meson.build logic
would suddenly enable extra features that would not have been built
otherwise. By allowing for explicitely enabling/disabling SDL2 and sndfile
depending bits, this problem is fixed.
