Fix --tail log on restart problem

Browse Source 
--tail=1 is not working f you restart a container with journald logging.

We see the exit status and then call into the logging a second time
causing all of the logs to print.

Removing the tail log on exited seems to fix the problem.

Fixes: https://github.com/containers/podman/issues/13098
