    reference: Fix docs to include the right header file
    
    docs says to include "gtk/gtkunixprint.h" for many APIs though "gtk/gtk.h"
    has to be actually included.
    
    This commit doesn't fix the underlying issue (which is probably an issue
    in gtk-doc), but the generated docs shows the right header file which is
    better than showing the wrong one.
    
    fixes https://gitlab.gnome.org/GNOME/gtk/issues/1318
