[PATCH] lib/gettext.h: fix warning if gettext is already present

[Giulio Benetti]

Building on an environment where gettext is already present leads to
emitting a warning about gettext_noop() alread defined. And if -Werror
is passed this warning will be treated like an error, so let's #undef
gettext_noop() before #define it.
