fixes to output of git-verify-pack -v

Now that the default delta depth is 50, it is a good idea to also bump
MAX_CHAIN to 50.

While at it, make the display a bit prettier by making the MAX_CHAIN
limit inclusive, and display the number of deltas that are above that
limit at the end instead of the beginning.
