KVM: selftests: Skip AMX test if ARCH_REQ_XCOMP_GUEST_PERM isn't supported

Skip the AMX test instead of silently returning if the host kernel
doesn't support ARCH_REQ_XCOMP_GUEST_PERM.  KVM didn't support XFD until
v5.17, so it's extremely unlikely allowing the test to run on a pre-v5.15
kernel is the right thing to do.
