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.
