build_repo_dir: "{{ ansible_user_dir }}" and ansible_user_dir is pointing to /root somehow and in order to create that directory at /root/DLRN the user does not have permission.
ansible_user_dir should point to home dir of the user not the root one.

    Make build-test-packages more resilient

    OVB failures due to
    - ansible_user variable was used instead of ansible_user_id, the first
    one being unreliable as is may only be user defined (or undefined).
    - lack of become on tasks that needed it

    Fixes problem identified by molecule testing
    - lack of idempotence on few tasks
    - failure when ansible_user variale was not defined
