Upgrade JGit to ad902087

This version contains the following fix:

Ensure that GC#deleteOrphans respects pack lock

If pack or index files are guarded by a pack lock (.keep file)
deleteOrphans() should not touch the respective files protected by the
lock file. Otherwise it may interfere with PackInserter concurrently
inserting a new pack file and its index.
