Keep fresh-install maintenance seed category in sync with Open group

add-app.sh had a separate Docker-install block that never got the AppArmor
fix from install-stack.sh's install_docker() (commit 9a45e39) — every app
added individually via add-app.sh since then was exposed to Docker builds
failing with "docker-default profile could not be loaded ... while confined".
Hit this deploying the calendar app to LXC 126 on the dev stack.
