    gtkdocize: allow settings gtkdocize options in more ways, Fixes 605564
    
    If one wants to e.g. use "--flavour no-tmpl" one needs to add that to
    autogen.sh. Gnome projects usualy use autogen.sh from gnome-common and thus
    can't do any customization. Now they can do it via envvar or via
    GTK_DOC_CHECK macro.
