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/multiarch/strcmp-power9.S: Likewise.
* sysdeps/powerpc/powerpc64/multiarch/strcmp-ppc64.S: Likewise.

* sysdeps/powerpc/powerpc64/multiarch/strncmp-ppc64.S: Likewise.
* sysdeps/powerpc/powerpc64/power4/strncmp.S: Set a default function
name if not defined and pass as parameter to macros accordingly.
* sysdeps/powerpc/powerpc64/power7/strcmp.S: Likewise.
