meson: properly handle gettext non-existence

Commit e91a49c9747f ("meson: don't build po if no gettext")
tried to add the possibility to build util-linux without gettext.

Unfortunately by default the call to find_program() would abort the
build if the program is not found.
Avoid aborting the build.
