mandos-ctl: Minimize number of D-Bus calls

* mandos-ctl (Command.run): Now takes a {objpath: properties} dict,
                            followed by optional "bus" and "mandos"
                            arguments.  Use "bus" to connect to
                            clients when dispatching to method
                            run_on_one_client().  All callers changed.
  (IsEnabledCmd.run): New.
  (IsEnabledCmd.run_on_one_client): Remove.
  (ApproveCmd.run_on_one_client): Add busname to debug output.
  (DenyCmd.run_on_one_client): - '' -
  (main): In D-Bus debug output, change "name" to "busname".  Also,
          don't connect to clients, just use the object path as the
          key of the "clients" dict passed to Command.run().
  (TestCmd.clients): Changed to an {objpath: properties} dict.
  (TestCmd.one_client): - '' -
  (TestCmd.bus): New mock bus object having a get_object() method.
