Today the rpm-ostree test suite uses `refs --create` to save
commits. I think this is a legitimate use case, and other
people may be doing something similar.
On the other hand, I think we should probably be changing the rpm-ostree test
suite to create "unbound" commits. But let's be maximially compatible here since
we hit a real-world case where something needed to change.

This new option verifies that the refs listed in the ref-bindings for
each commit all point to that commit (i.e. there aren’t multiple commits
listing the same ref in their ref-bindings, and there aren’t any commits
with non-empty ref-bindings which aren’t pointed at by a ref).
This is useful when generating a new repository from scratch, but not
useful when adding new commits to an existing repository (since the old
commits will still, correctly, have ref-bindings from when the refs
pointed at them). That’s why it has to be enabled explicitly using
--verify-back-refs, rather than being on by default.
