config: let NMConfig handle "NetworkManager.state" file (bgo#764474)

Move reading and writing of the state file to NMConfig
("/var/lib/NetworkManager/NetworkManager.state" file).

Originally, I intended to persist more state, thus it made
sense to cleanup handling of the state file and move it all
at one place. Now, it's not clear that will happen anytime soon.

Still, the change is a worthy cleanup, so do it anyway.
