builtin/verify-pack: implement an --object-format option
A recently added test in t5702 started using git verify-pack outside of
a repository. 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.
