The entrypoints in Docker Image should be owned by Airflow (#10853)

Since we are running the airflow image as airflow user, the
entrypoint and clear-logs scripts should also be set as airflow.

This had no impact if you actually run this as root user or
when your group was root (which was recommended).

(cherry picked from commit d9920fa)
