shout: copy the audio_format, instead of taking a pointer

Browse Source 
Storing pointers to immutable audio_format structs isn't worth it,
because the struct itself isn't much larger than the pointer.  Since
the shout plugin requires the user to configure a fixed audio format,
we can simply copy it in myShout_initDriver().
