jenkins-job.sh: show git log at the beginning of each build job (v1.8…

….30)

* use the same function as at the end of the report, but include it
  just after updating the checkouts, so that when different MACHINEs
  are built from different metadata it's easier to find out what
  exactly was included in given build
