MacOS: create_cstr_from_cfstring uses safe conversion - use CFStringGetCString

Browse Source 
During testing with gdk-pixbuf I noticed failures during content type
to mime conversion. The root reason was the unsafe conversion used
in create_cstr_from_cfstring. The problem was addressed in commit
c60226e0a1 but that was reverted. I noticed the commit only
when I had fixed the problem. In addition I added a test to check
the content type to mime conversion on MacOS. This problem is
discussed in Bug #788936.
