tool: Correctly print timed out event scripts output

The timed out error is ignored for certain events (start_recovery,
recoverd, takeip, releaseip).  If these events time out, then the debug
hung script outputs the following:

 3 scripts were executed last releaseip cycle
 00.ctdb              Status:OK    Duration:4.381 Thu Jul 16 23:45:24 2015
 01.reclock           Status:OK    Duration:13.422 Thu Jul 16 23:45:28 2015
 10.external          Status:DISABLED
 10.interface         Status:OK    Duration:-1437083142.208 Thu Jul 16 23:45:42 2015

The endtime for timed out scripts is not set.  Since the status is not
returned as -ETIME for some events, ctdb scriptstatus prints -ve duration.
