wayland: do not update shadows for child windows

glade-previewer places a gtkwindow inside another toplevel gtkwindow,
updating the shadow width for the client induces a busy loop where the
parent will grow continuously until it crashes gnome-shell/mutter.

To avoid the loop, do not update the shadow width if not dealing with a
toplevel window.
