Always use gtk_window_move in new versions

* src/gtkutil.c (my_log_handler): Don’t define in new versions of
GTK+.
(xg_set_geometry): Always use gtk_window_move in new versions of GTK+.

* src/xterm.c (syms_of_xterm): Document that x-gtk-use-window-move
is ignored.

* lisp/subr.el (x-gtk-use-window-move): Make obsolete.
