    Exclude a file when generating gtk_docs.xml
    
    * tools/gen_scripts/gtk_generate_docs.sh: Exclude gtkdnd-quartz.c.
    Function documentation in gtkdnd-quartz.c can replace better documentation
    in gtkdnd.c, if docextract_to_xml.py is allowed ot process gtkdnd-quartz.c.
    This patch requires a glibmm version where docextract_to_xml.py accepts
    the newly added -x option.
