tests/docker: Refresh APT cache before installing new packages on Debian

Since docker caches the different layers, updating the package
list does not invalidate the previous "apt-get update" layer,
and it is likely "apt-get install" hits an outdated repository.

See commit beac6a98f6eb and
https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get
