Mac: fix double free

Browse source 
Had wrongfully assumed CFStringRef's were reference counted
objects that needed to be CFRelease()'d when we no longer
needed them.

However according to the CFArrayGetValueAtIndex() API docs
( https://developer.apple.com/documentation/corefoundation/1388767-cfarraygetvalueatindex?language=objc )
it follows "get rule" for memory ownership, meaning it is not
ours to release.

Only prefLangs returned by CFLocaleCopyPreferredLanguages()
need to be CFRelease()'d as that does follow "create rule"
