bug#31223: 25.3; New menus are empty with GTK3

[Thomas Schneider]

When changing to a mode that provides new menus (e. g. AUCTeX), new
menus appear in the menu bar (LaTeX and Command in this case), but they
appear empty.  This is only the case with GTK3; GTK2, Motif and terminal
do not show this behaviour.

In fact, it looks very much like bug#4122, just for GTK3 instead of
GTK2.  Launching Emacs with GDK_NATIVE_WINDOWS=1 as suggested in
lp#415101 does not help.
