ts3audiobot: Adjust directory permissions

This patch reduces the permissions on the install directory to just the root user and also fixes the ansible-lint issue by specifying the `mode`.
For all container mounted volumes, the ansible-lint rule is disabled, as the container takes care of the permissions etc.
