get_ref_dir(): require that the dirname argument ends in '/'

Browse source 
This removes some conditional code and makes it consistent with the
way that direntry names are stored.  Please note that this function is
never used on the top-level .git directory; it is always called for
directories at level .git/refs or deeper.
