x86-64: Fold ifunc-sse4_1.h into wcsnlen.c
Since ifunc-sse4_1.h is included only by wcsnlen.c, we can fold it
into wcsnlen.c. No code changes in wcsnlen.o.

* sysdeps/x86_64/multiarch/ifunc-sse4_1.h: Removed and folded
into ...
* sysdeps/x86_64/multiarch/wcsnlen.c: Here. Don't include
ifunc-sse4_1.h.
