Update JGit to 5.0.0.201806131550-r

JGit 5.0.0 introduces some new features (including support for the
git protocol v2), performance improvements, and bug fixes.

It also includes a number of deprecations, some of which cause
warnings in the gerrit project. These are not fixed in this commit,
but will be fixed in follow-ups.

See the release notes [1] for full details of the release.
