c++/modules: Fix ICE in instantiating_tu_local_entity [PR122628] 

I'd missed a STRIP_TEMPLATE when attempting to query whether DECL was
an imported entity.

	PR c++/122628

gcc/cp/ChangeLog:

	* module.cc (instantiating_tu_local_entity): Add missing
	STRIP_TEMPLATEs.

gcc/testsuite/ChangeLog:

	* g++.dg/modules/internal-18.C: New test.
