[PATCH] D26267: [Modules] Include builtins with #include instead of #import for ObjC

After r284797 builins are treated like textual includes. When compiling for ObjC++, the in-memory header file generated for the modules is composed only of #import's instead of includes. That could block some textual includes to happen because #import's will not re-enter headers already handled by other #import's.

Use #include when the header in question is a built-in.
