Subject: [PATCH 1/2] gnetworkmonitornm: Stop using removed PropertiesChanged
signal
Use the org.freedesktop.DBus.Properties interface to listen
to PropertiesChanged signals on /org/freedesktop/NetworkManager.
NetworkManager used to provide its own legacy PropertiesChanged
signal, but that was dropped in
https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/853
This requires NetworkManager >= 1.2 (2016)
Fixes: #2505

Subject: [PATCH 2/2] gnetworkmonitornm: Do not re-update cached property
GDBusProxy already takes care of updating the cached property
before emitting the signal, so there is no need to do this
a second time ourselves.
