The patch d8cbe8bfa7d tries to include a ARCH check for powerpc,
however ARCH is not defined in the Makefile before including
lib.mk. This makes test building to skip on both x86 and powerpc.
Fix the arch check by replacing it using machine type as it is
already defined and used in the test.

Fixes: d8cbe8bfa7d ("tools/testing/selftests/vm: fix build error")
Signed-off-by: Harish <harish@linux.ibm.com>
---

Changes from v1:
 - Add cause for test skip
 - Handle x86_64 architecture
 - Minor fixes to handle ppc64/ppc64le
 - Add Fixes tag

The findstring isn't really canonical, it's my fault,
you can replace findstring with filter like V1.
