Upgrade JGit to 4.3.0.201604071810-r

this version brings the following fixes

- Fix jgit gc which retained garbage packs for 2 weeks which resulted
in repo size explosion [1] by introducing a new option for pack expiration
which by default expires packs after 1 hour

- Fix refcounting and reclaiming memory in RepositoryCache. Hugo
validated that this reduces memory consumption in Gerrit considerably

- Make the FileLfsRepository thread safe. This fixes a severe threading
issue for the lfs-storage-fs plugin [2]
