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.

2017-06-07  H.J. Lu  <hongjiu.lu@intel.com>

	* 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.
