Update JGit to 3.6.2.201501210735-r

This version of JGit logs IOExceptions caught while accessing pack files
and only removes affected packs from the pack list if we know that the
pack is corrupt. Other IOExceptions could be transient hence JGit
doesn't remove the affected pack from the list anymore to avoid the
problem reported on the Gerrit list [1]. It looks like in the reported
case the pack was removed from the pack list causing
MissingObjectExceptions which disappear when the server is restarted.
