  AppArmor hooks incorrectly build query string for receiving process

Bug description:
  While reviewing the AppArmor hooks in dbus-daemon, I noticed that the AppArmor
  query string for the receiving process was being constructed incorrectly in
  dbus 1.6.12-0ubuntu5.

  Here's the query for the sending process. Note that the message destination is
  used for the AppArmor query's peer name (the fourth parameter):

        qsize = build_query (&qstr, scon->context, bustype, destination,
                             tcon->context, path, interface, method);

  Here's the query for the receiving process. Note that the message destination
  is still being used for the AppArmor query's peer name. This is incorrect
  because the peer of the receiving process is the sender.

        qsize = build_query (&qstr, tcon->context, bustype, destination,
                             scon->context, path, interface, method);
