powerpc: Fix IFUNC for memrchr
Recent commit 59ba2d2b5421 missed to add __memrchr_power8 in
ifunc list. Also handled discarding unwanted bytes for
unaligned inputs in power8 optimization.

* sysdeps/powerpc/powerpc64/multiarch/memrchr-ppc64.c: Revert
back to powerpc32 file.
* sysdeps/powerpc/powerpc64/multiarch/memrchr.c
(memrchr): Add __memrchr_power8 to ifunc list.
* sysdeps/powerpc/powerpc64/power8/memrchr.S: Mask
extra bytes for unaligned inputs.
