powerpc: Optimized strncat for POWER7/PPC64

With 3eb38795dbbbd816 (Simplify strncat) the generic algorithms uses
strlen, strnlen, and memcpy.  This is faster than POWER7 current
implementation, especially for unaligned strings (where POWER7 code
uses byte-byte operations).

This patch removes the assembly implementation and uses a multiarch
specialization based on default algorithm calling optimized POWER7
symbols.
