    thunderbolt: react to security level changes
    
    Listen for security level changes, which in theory should not really
    happen at all with the exception that on hardware where force power
    is not support and boltd has not yet seen the thunderbolt controller
    because it was powered down. Then we should get an initial change
    from 'unknown' to the real level. Handle it in the same way that
    as if boltd was restarted, i.e. the dbus name owner changed
