x86/bugs: Add missing NO_SSB flag

The Moorefield and Lightning Mountain Atom processors are
missing the NO_SSB flag in the vulnerabilities whitelist.
This will cause unaffected parts to incorrectly be reported
as vulnerable. Add the missing flag.

These parts are currently out of service and were verified
internally with archived documentation that they need the
NO_SSB flag.
