Removing the hostname to the job commit.

pbs_submit.sh was changed for slurm support to only look at
the job id numbers, not at the hostname (slurm output is weird).
pbs_status.py would look for the entire jobid, with hostname, but
the gahp would only give the number, therefore pbs_status.py
could not find the job.
