xdgmime: fix special case for mime_type_subclass

Browse Source 
Currently, all mime types are considered subclasses of
application/octet-stream, but according to the freedesktop
standard, everything but the inode/* types is a subclass of
application/octet-stream.

Update the special case for application/octet-stream so that all
types but inode/* will match with it and add unit test for it.
