dockerhub rate limits our image pulls; switch to containers.torproject.org and remove all the things we do not have images for (leaves only modern debians and only amd64

Try to work around broken build results because runners go away.

(commit 301553ce from tor debian-main)

Switch binary artifact retention time to 1 hour (from 1 week) as we keep the most successful one anyway

Revert "Add some debug output to &apt-init" and "remove elements in /var/lib/apt/lists if apt-get update fails and retry"

This reverts commit 6cf5eb74.
This reverts commit 758db626.

The issues we encountered were caused by a full filesystem on a
gitlab-ci runner.

We run into apt update errors such as:

  Get:1 http://deb.debian.org/debian sid InRelease [165 kB]
  Err:1 http://deb.debian.org/debian sid InRelease
    At least one invalid signature was encountered.
  Reading package lists...
  W: GPG error: http://deb.debian.org/debian sid InRelease: At least one invalid signature was encountered.
  E: The repository 'http://deb.debian.org/debian sid InRelease' is not signed.

Let's see if setting APT::Acquire::Retries does anything to prevent
those.
