[bitnami][clickhouse] Correct ClickHouse behavior when user adds custom init/start script

Description of the change

In bitnami/clickhouse 24.8.4-debian-12-r0, when user tries to run custom init/start script (in my case - create a new Database). ClickHouse cannot execute that scripts and cause the container to crash.
