Move pa_format_info_to_sample_spec_fake() to core-format

Browse source 
I will need to use the function from outside libpulse.

I added the channel map argument, because the function will be called
from another function that is expected to initialize the channel map.
I don't know if it's in practice necessary, but it shouldn't do any
harm either.
