    Fix reference documentation generation
    
    * docs/Makefile.am: Include the filelist.gmake.am files if applicable
    * glib/glibmm/filelist.gmake.am:
    * gio/src/filelist.gmake.am:
    * gio/giomm/filelist.gmake.am: Include filelist.am relative from
    $(top_srcdir) as we are including the filelist.gmake.am's from docs/
    as well.
