make interpreter targets and dirstamp files order-only prerequisites

* doc/module.mk, libgui/graphics/module.mk, libgui/module.mk,
libgui/qterminal-module.mk, libgui/src/module.mk,
scripts/java/module.mk, src/module.mk, test/module.mk:
Make the $(OCTAVE_INTERPRETER_TARGETS) and dirstamp files order-only
prerequisites for other files since we only need for them to exist.
