Improve socket-activated service handling

This patch provides a more generic way of handling socket-activated
services like dropbear. A socket-activated service only has base socket
unit and spawns service unit with instance name on incoming connection,
so the instanced units of it need to be ignored. And whether a service
is socket-activated can be determined by checking the existance of its
service object path.

Tested:
* Two socket-activated service, dropbear and obmc-console-ssh, can be
  controlled as expected.
* Instances of socket-activated services are no loger added to monitor
  list.
