When running under older versions of qemu of under newer versions with old machine types, some security features will not be reported to the guest. This will lead the guest OS to consider itself Vulnerable to spectre_v2. So, spectre_v2 test fails in such cases when the host is mitigated and miss predictions cannot be detected as expected by the test. Make it return the skip code instead, for this particular case. We don't want to miss the case when the test fails and the system reports as mitigated or not affected. But it is not a problem to miss failures when the system reports as Vulnerable.
