Draft: explicit build-time packge dependencies

Seen @ https://github.com/docker-library/python/blob/7899dbafd386ee264bd33574aafcd0f1369b2e21/3.11/slim-bullseye/Dockerfile#L33
Instead of installing all recommended packages, we explicitly mention what we need.
It reduces the download of 10's of build-time dependencies.

What I'm not sure of - are we missing features, that are not compiled as deps are not found?
(encryption comes to mind).
