main: (order) early start D-Bus service

Browse source 
systemd considers the startup time of NetworkManager until the D-Bus
service is claimed. By doing that earlier, this time is significantly
reduced.
This has the advantage, that services that are ordered to start
after NetworkManager can start earlier. Most notably, 'network.target'
orders itself After=NetworkManager.service and many services are ordered
After=network.target.

  $ systemd-analyze blame | grep NetworkManager.service
