t/run.perl: less confusing error reporting

The $sigchld handler was reporting the last test (successful or
not) for a given PID in case a worker dies prematurely.
Instead, redisplay all failed test in $run_log to ensure the
report only shows failed tests, and not the last started (and
possibly successful) one.
