rtnetlink_server: Refresh for route changes

We want to make sure we update the DefaultGateway if it changes.
Otherwise when someone changes our gateway we don't update the state of
the phosphor-network daemon.

Tested:
    Editted the default route manually through netlink and saw the
    update get picked up in the dbus interface.
