Bug#911563: ITP: pystemd - Cython-based wrapper on top of libsystemd

[Alexandros Afentoulis]

I actually fixed autopkgtest in Salsa by simply using CI team's pipeline 
predefined jobs. They've done great work there.

https://salsa.debian.org/python-team/modules/pystemd/pipelines/68325
So please take a look at the package and let me know how to proceed.

Cheers,
Alex
