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

# timeout set to 45
# selftests: x86: amx_64
# # xstate cpuid: invalid tile data size/offset: 0/0
ok 42 selftests: x86: amx_64 # SKIP
# timeout set to 45
# selftests: x86: lam_64
# # Unsupported LAM feature!
ok 43 selftests: x86: lam_64 # SKIP
...
In amx test, Move away from check_cpuid_xsave() and start using
arch_prctl() to find out if amx support is present or not. In the
kernels where amx isn't present, arch_prctl returns -EINVAL. Hence it is
backward compatible.
