Restrict VPN Diagnostics callbacks to underlying networks.

ConnectivityDiagnosticsCallbacks should only be invoked for the
underlying networks declared by active VPNs. This encourages VPN apps to
declare their underlying networks.

The previous permission model for VPNs allowed active VPNs to receive
callbacks on any network.
