Title: Upgrade git version used on the Jenkins worker

GitHub requires version 1.7.10 or later, but we were using a slightly older version. I think this may be responsible for the three times I've observed the Jenkins git plugin hanging on `git fetch`.

By adding the git-core apt-repo, we will use git version 1.8.4.
