rs6000: Fix up c-c++-common/builtin-classify-type-1.c failure [PR112725]

Browse source 
The rs6000 backend (and s390 one as well) diagnoses passing vector types
to unprototyped functions, which breaks the builtin-classify-type-1.c test.
The builtin isn't really unprototyped, it is just type-generic and accepting
vector types is just fine there, all it does is categorize the vector type.
The following patch makes sure we don't diagnose it for this builtin.

	PR target/112725
	* config/rs6000/rs6000.cc (invalid_arg_for_unprototyped_fn): Return
	NULL for __builtin_classify_type calls with vector arguments.
