Fixed MariaDB template evaluation used for TLS

[WillDyson]

Originally, for MariaDB, the playbook wrote the evaluated template cloudera.cnf.j2 to /tmp/cloudera.cnf on the database hosts. The MariaDB collection would then search for this file on the ansible controller – causing an error in most cases.
As the RDBMS collection already calls template when copying this file, we do not need to evaluate it eagerly.
This PR removes the evaluation of the template and fixes the bug described above.
