auth-manager: re-use D-Bus connection from NMDBusManager

Browse source 
First of all, NMDBusManager takes the system D-Bus connection synchronously, so we
should avoid API that is asynchronous and first needs to get glib's G_BUS_TYPE_SYSTEM
instance.

Also, the only reason why NMDBusManager might not have a D-Bus connection is in "initrd"
configure-and-quit mode. In that mode we also don't need polkit.
