Merge ~cjwatson/launchpad-buildd:unpin-python-debian into launchpad-buildd:master

Unversion python-debian requirement

The minimum version required was very old (pre-xenial), so the version constraint was no longer really necessary. Furthermore, the version of the packaged python-debian in >= focal confuses modern pip/setuptools (see https://bugs.launchpad.net/bugs/1926870); removing the version constraint avoids needing to care about this.
