Skip instead of failing when prerequisite conditions aren't fulfilled, such as invalid xstate values etc. This patch would make the tests show as skip when run by: make -C tools/testing/selftests/ TARGETS=x86 run_tests

In the kernels where amx isn't present, arch_prctl returns -EINVAL. Hence it is backward compatible.
