[xcode] Make sample rate + channels variable

Browse Source 
This change is preparation to use ffmpeg's resampling capabilities to keep local
audio in sync (by up/downsampling slightly). This requires that sample rates are
not fixed for a transcode profile.

Added benefit of this is that we don't need quite as many xcode profiles.
