mandos-ctl: Eliminate unnecessary D-Bus call
* mandos-ctl (command.Base.run): Don't set self.mandos.
(command.Remove): Implement .run() instead of .run_on_one_client()
to avoid the command.Base.run() unnecessarily
connecting to a client object.
* mandos-ctl (command.Base.run): Don't set self.mandos.
