Subject: selftests/vm: skip 128TBswitch on unsupported arch
Date: Mon, 4 Jul 2022 14:38:13 +0200

The test va_128TBswitch.c exercises a feature only supported on PPC and
x86_64, but it's run on other 64-bit archs as well.  Before this patch,
the test did nothing and returned 0 for KSFT_PASS.  This patch makes it
return the KSFT codes from kselftest.h, including KSFT_SKIP when
appropriate.

Verified on arm64 and x86_64.
