powerpc: Optimized strncat for POWER8
With new optimized strnlen for POWER8 [1], this patch adds
strncat for power8 to make use of optimized strlen and strnlen.
This is faster than POWER7 current implementation for larger strings.
Tested on powerpc64 and powerpc64le.

* sysdeps/powerpc/powerpc64/multiarch/Makefile (sysdep_routines): Add
strncat-power8.
* sysdeps/powerpc/powerpc64/multiarch/strncat.c (strncat): Add
__strncat_power8 to ifunc list.
* sysdeps/powerpc/powerpc64/multiarch/ifunc-impl-list.c
(strncat): Add __strncat_power8 to list of strncat functions.
* sysdeps/powerpc/powerpc64/multiarch/strncat-power8.c: New file.
