Convert StatusBarModel to get WiFi status info from network binding

The StatusBarModel updates icons using an exposed DBus API that
avoids the appfw. The new networking binding does not support the
out of band StatusBar DBus API. Use events from the network binding
(exposed as Qt properties) to update the WiFi status indicator.

Bug-AGL: SPEC-1628
