t5316: check behavior of pack-objects --depth=0

We'd expect this to cleanly produce no deltas at all (as opposed to getting confused by an out-of-bounds value), and it does. Note we have to adjust our max_chain test helper, which expected to find at least one delta. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
