Option --show fix

[richtja]

This adds the ability for the runners to print user-specific logging streams to the console when the --show command is used.

It is backport of https://github.com/avocado-framework/avocado/commit/e2652b71668068838ea856bb7e16b262d34a511e and https://github.com/avocado-framework/avocado/commit/ddd143e2e928fa326dcd9ee65a942087207c5748.

@richtja I took a quick look to the failure of debian_version container:ubuntu:18.04 . I didn't find exactly why it fails, but it seems for older distros it needs pinning markupsafe, see: https://github.com/avocado-framework/avocado/pull/5321

Hi @clebergnu I did a rebase to apply your changes from #5485, which fixes the CI problems. Can you please review this when you will have a time. Thanks.
