Wallabag/mariadb healthcheck fails: mysqladmin is not included in the official container

[jeff47]

The healthcheck statement in the docker compose example fails, because mysqladmin is not included in the official mariadb container.

I think the new format should be

      healthcheck:
            test: ['CMD', '/usr/local/bin/healthcheck.sh', '--innodb_initialized']
            start_period: 5s
            timeout: 5s
            interval: 5s
            retries: 5

The new format fixed the UNHEALTHY tag for me.

Could you open a PR to fix it then? Thanks.
