gtkimagemenuitem: create widget for action icons lazily

Browse Source 
GtkImageMenuItem always packs a GtkImage when it is synced with a
related action. This is unnecessary when the action doesn't have an icon
set and results in excess padding when a GtkImageMenuItem is put in a
menu bar (GtkUIManager does this).

Fix this by not creating the GtkImage for icon-less actions.
