Filter another line of slurm output for lulesh failure cases.

This only occurs with the ugni comm layer.
fix typo
Merge branch 'master' of github.com:chapel-lang/chapel into slurm-ugni-lulesh-prediff
Merge pull request #391 from thomasvandoren/slurm-ugni-lulesh-prediff

Update lulesh prediff for slurm ugni configuration.

When running lulesh tests with slurm launcher, ugni comm, and muxed tasks the following error shows
up in addition to the regular non-zero exit code error:

```
slurmstepd: Terminating job step 113904.0; task 0 exit code 1 exited without notification
```

This updates the prediff to filter this message, too.

I tested that the lulesh tests pass on my mac as well as on an XC with the configuration that this error
shows up in.
