self-hosted testbed: add openssh-client, jq, rsync

These come up routinely in CI workflows: openssh-client for any git-over-ssh deploy step (broke deploy-antora-docs), jq for any JSON-shaping bash, rsync for tree copies. wget was already present. Bake them in once instead of letting each migrating workflow apt-get them per job.
