Upgrade JGit to 5.1.5.201812261915-r

This release fixes an issue where AdvertiseRefsHook was not called for
git-upload-pack in protocol v0 bidirectional transports, meaning that
wants aren't validated and a user can fetch anything that is pointed
to by any ref (using fetch-by-sha1), as long as they can guess the
object name.
