dbus: don't even bother connecting in configure-and-quit mode

It makes no sense, results in unnecessary complexity both in code and in
code comments.

/* we will create the D-Bus connection and registering the name synchronously.
* The reason why that is necessary is because:
* (1) if we are unable to create a D-Bus connection, it means D-Bus is not
* available and we run in D-Bus less mode. We do not support creating
* a D-Bus connection later on. This disconnected mode is useful for initrd
* (well, currently not yet, but will be).
* (2) if we are able to create the connection and register the name,
* all is good and we run with D-Bus. Note that D-Bus disconnects
* from D-Bus are ignored. Essentially, we do not support restarting
* D-Bus.
* (3) if we are able to create the connection but registration fails,
* it means that something is borked. Quite possibly another NetworkManager
* instance is running. We need to exit right away.
* To appease (1) and (3), we cannot initialize synchronously, because we need
* to know right away whether another NetworkManager instance is running (3).
/* Create the D-Bus connection and registering the name synchronously.
