We check our templates to make sure they are from a
version of git we understand (otherwise we would init a
repository we cannot ourselves run in!). But our simple
integer check has fallen behind the times. Let's use the
helpers that setup.c provides to do it right.

I actually wonder if this code has been triggered ever, in the history
of git. We do not ship a "config" file in our templates, and I doubt
that anybody would ship one that sets core.repositoryformatversion.
