S390: Refactor wcsncat ifunc handling.
The ifunc handling for wcsncat is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.

ChangeLog:

	* sysdeps/s390/multiarch/Makefile
	(sysdep_routines): Remove wcsncat variants.
	* sysdeps/s390/Makefile (sysdep_routines): Add wcsncat variants.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Refactor ifunc handling for wcsncat.
	* sysdeps/s390/multiarch/wcsncat-c.c: Move to ...
	* sysdeps/s390/wcsncat-c.c: ... here and adjust ifunc handling.
	* sysdeps/s390/multiarch/wcsncat-vx.S: Move to ...
	* sysdeps/s390/wcsncat-vx.S: ... here and adjust ifunc handling.
	* sysdeps/s390/multiarch/wcsncat.c: Move to ...
	* sysdeps/s390/wcsncat.c: ... here and adjust ifunc handling.
	* sysdeps/s390/ifunc-wcsncat.h: New file.
