Make lando db-export use mariadb-dump, if it exists (#148)

* Make `lando db-export` use mariadb-dump, if exists

`mysqldump` is deprecated in current versions of MariaDB, and generates a
deprecation warning. This change allows `db-export` to use `mariadb-dump`
if that command exists and the `MARIADB_DATABASE` env var is set.

Resolves lando/mariadb#47

* Fix typo in sql-export.sh comment

* Update CHANGELOG.
