You can as well leave the braces empty as nothing is tested here right now. If
there is a corresponding pref (I think there isn't) or some UI in the settings
that is changed when this policy is triggered it can be tested here but
otherwise leaving just 

"Http09OnNonDefaultPortsEnabled": {}

to satisfy the presubmit is good enough.

Done (Yea, there's no pref, no UI surface area)
