Bug#1061426: opm-common ftbfs with Python 3.12 as the default

[Matthias Klose]

Package: src:opm-common
Version: 2023.04+ds-5
Severity: serious
Tags: sid trixie ftbfs
User: debian-python at lists.debian.org
Usertags: python3.12

ftbfs with python3-defaults from experimental

the package builds, then fails in the tests.

there is also a b-d on python3-distutils, which is gone in 3.12, and 
apparently not needed.

please see the build logs at
https://launchpad.net/ubuntu/+source/opm-common/2023.04+ds-5ubuntu2
