While the GtkSettings::gtk-shell-shows-app-menu property is meant to reflect a desktop capability (i.e. in the GNOME case: the app menu is shown in the top bar), it is possible for users to overwrite it. Respect the setting and actually hide the menu in that case. https://bugzilla.gnome.org/show_bug.cgi?id=745919
