Thanks, Michael. The upcoming features for dpkg to handle
bootstrapping better look interesting, but nothing in the archive
currently uses them.

For the moment, I've opted to patch objx to avoid any use of testify.
That was fairly easy, although it will be painful if upstream
is going to be changing frequently.
