localectl: support systems without locale-archive
Not all systems ships with locales inside /usr/lib/locale-archive, some prefer to have locale data as individual subdirectories of /usr/lib/locale. (A notable example of this is OpenEmbeddded, and OSes deriving from it like gnome-ostree). Given that glibc supports both ways, localectl should too.
