Merge near-duplicated (grand)parent finding code

Besides avoiding near-duplication, this avoids having three generations of
certificate (child, parent, grandparent) in one function, with all the
off-by-one opportunities that come with it.

This also allows to simplify the signature of verify_child(), which will be
done in next commit.
