mysql-8.0/Dockerfile: Update Mroonga and Groonga versions

When mysql-community-8.0-mroonga is installed, mysql-community-server is installed as a dependency.
At that time, the initialization process is also executed, and the initialization process of `docker-entrypoint.sh` is not executed.
Therefore, `rm -rf /var/lib/mysql` is added.
