powerpc: Zero pad using memset in strncpy/stpncpy

Call __memset_power8 to pad, with zeros, the remaining bytes in the
dest string on __strncpy_power8 and __stpncpy_power8.  This improves
performance when n is larger than the input string, giving ~30% gain for
larger strings without impacting much shorter strings.
