* In 0.9 the entrypoint got removed as it's recommended to use
`python -m`[1]. However, our build layer for python relies on
that, so I added a patch to re-add this.
* The tests in the upstream sources appear abandoned, so those are
skipped. Therefore it's also pointless to add `pytest-runner` to the
`nativeBuildInputs` as it's not used and only blows up the build
closure.
A second patch modifies the requirements, so ow `pytest-runner` isn't
needed anymore.
