[PATCH] rcutorture: tag success/failure line with module parameters

A long-running rcutorture test can overflow dmesg, so that the line
containing the module parameters is lost.  Although it is usually possible
to retrieve this information from the log files, it is much better to just
tag it onto the final success/failure line so that it may be easily found.
This patch does just that.
