powerpc: refactor strcasecmp, strcmp, and strncmp IFUNC.

Clean up the IFUNC implementations for powerpc in order to remove
unneeded macro definitions.

Tested on ppc64le with and without --disable-multi-arch flag.

	* sysdeps/powerpc/powerpc64/multiarch/strcasecmp_l-power7.S: Define
	the implementation-specific function name and remove unneeded
	macros definition.
	* sysdeps/powerpc/powerpc64/multiarch/strcmp-power7.S: Likewise.
	* sysdeps/powerpc/powerpc64/multiarch/strcmp-power8.S Likewise.

	* sysdeps/powerpc/powerpc64/power4/strncmp.S: Set a default function
