While this poses no problems with SHA-1, with SHA-256 we implicitly rely on the setup of the repository to initialize our hash algorithm settings. 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 we're now dynamically adjusting the elements in argv, let's switch to using struct argv_array to manage them. Finally, let's make t5702 pass the proper argument on down to its git verify-pack caller.
