Mount always ref/secrets. (helm#23137)

The `ref/secrets` is mounted only when `master.enableXmlConfig == true`.
This is bug. The `ref/secrets` must be always mounted. Just because

`master.secretsFilesSecret` and `master.enableXmlConfig` are unrelated, as well as:

./templates/config.yaml has unconditional:

  apply_config.sh: |-
    echo "applying Jenkins configuration"
    mkdir -p {{ .Values.master.jenkinsRef }}/secrets/;

This mkdir will fail in UID != 0.
We need to mount always secrets.
