typefinding: disable typefinder for headerless flac

Browse source 
Disable headerless flac typefinder as long as it happily typefinds anything
including /dev/urandom as flac and as long as it's not particularly useful
given that such streams don't really exist in the wild.

Also fix up some comments so that gtk-doc doesn't complain about them.
