Hans-Christoph Steiner 7988c54d00 buildserver: always use HTTPS for apt connections in Docker image
This configuration has been in use in .gitlab-ci.yml scripts for a while
now and has proven reliable.  This is a "low hanging fruit" improvement.
It provides an extra layer of protection for when their are apt vulns.  And
it makes it much harder to profile what a server/laptop is doing based on
the internet traffic.  The network observer will no longer be able to see
which packages are being downloaded since apt uses HTTP pipelining so size
attacks are not really possible. And HTTPS hides the URLs, filenames,
download contents, etc.

#
# The official Debian docker images ship without ca-certificates, so
# TLS certificates cannot be verified until that is installed. The
# following code temporarily turns off TLS verification, and enables
# HTTPS, so at least unverified TLS is used for apt-get instead of
# plain HTTP. Once ca-certificates is installed, the CA verification
# is enabled by removing the newly created config file. This set up
# makes the initial `apt-get update` and `apt-get install` look the
# same as verified TLS to the network observer and hides the metadata.
