systemd: don't make NetworkManager D-Bus activatable

If the NetworkManager daemon has been stopped manually we don't want it
to be autostarted by a client request.

[lkundrak@v3.sk: The auto-activation is probably more surprising than useful.
Services that need NetworkManager API should depend on NetworkManager service
directly.

I have no idea what purpose does the D-Bus service file serve nowadays,
but it looks rather hacky (really, activating /bin/false) and the comment
in it suggests that the autoactivating behavior was not intended anyway.
Debian has been shipping this for quite some time and no complains have been
heard.]
