* Don't delete the mariadb.sys yser
Since 10.4.13 `mysql.user` (and probably others) have a new definer `mariadb.sys` instead of `mysql.sys` that should be added to the list of users which are retained.
The Docker library has fixed their bootstrap code in https://github.com/docker-library/mariadb/pull/306 - this change applies the same fix here.
* Bump version
* Update CHANGELOG.md
