Subject: [PATCH] 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.
