check the master_fd

Display Server(Enlightenment) always use the master_fd, so if the process can get the
master_fd from tbm_drm_helper_get_master_fd(), there is no need to get
the authentication information.
If the process does not have the master_fd, it needs to get the
authentication from the master process which is the Display
Server(Enlightenment).
