Re: [PATCH v3 30/39] builtin/verify-pack: implement an --object-format option

Since we're not in a repository here, we need to provide git verify-pack
help to set things up properly.  git index-pack already knows an
--object-format option, so let's accept one as well and pass it down to
our git index-pack invocation.  Since this argument is optional, let's
dynamically determine the proper location to insert it into the array.
Finally, let's make t5702 pass the proper argument on down to its git
verify-pack caller.
