selftests/mm: fix powerpc ARCH check
commit 7e6423441b36e3a03907e2df84b73c414c9c3763 upstream.
In commit 0518dbe97fe6 ("selftests/mm: fix cross compilation with LLVM")
the logic to detect the machine architecture in the Makefile was changed
to use ARCH, and only fallback to uname -m if ARCH is unset. However the
tests of ARCH were not updated to account for the fact that ARCH is
"powerpc" for powerpc builds, not "ppc64".
Fix it by changing the checks to look for "powerpc", and change the
uname -m logic to convert "ppc64.*" into "powerpc".
With that fixed the following tests now build for powerpc again:
* protection_keys
* va_high_addr_switch
* virtual_address_range
* write_to_hugetlbfs
