meson: do not reference variable unless feature that defines it is enabled

SYSTEMD_LANGUAGE_FALLBACK_MAP is used by the localed test, and
language_fallback_map is defined by the localed meson.
If the feature is disabled, the test is not built so the env var
is not needed, and the meson variable is not defined so the build
fails.
