Label daemon is not locale-aware (4384632)

The label daemon, labeld, always operates in the C locale.

Workaround: In locales where upper/lower case are not a direct mapping of the C locale, the classification and word names, short names, and alternate names in the label_encodings(4) file and all string labels in all databases must be in upper case only. Also, all labels must be entered in upper case only.
