knownneetworks: React to mtime updates

Browse Source 
We track mtime as the 'LastConnectedTime' of the network, and also sort
the known network list according to the last connected time.
Unfortunately we were never reacting to ATTRIB changes, and so were
never updating the network_info->connected_time whenever a network was
connected to.

Rework the logic to address this.  This also fixes a small bug where the
connected_time was not set properly prior to removal / re-insertion of
the network_info.
