selftests/vm: skip 128TBswitch on unsupported arch
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.
