[PATCH] nl_langinfo: pacify gcc -Wunused-function

[Paul Eggert]

* lib/nl_langinfo.c (ctype_codeset): Do not define if
REPLACE_NL_LANGINFO && !GNULIB_defined_CODESET, as it is unused in
this case. Without this change, I got a diagnostic when building
coreutils on Fedora 27 with gcc 7.3.1 20180130.
