string: Fix tester build with fortify enable with gcc < 12
When building with fortify enabled, GCC < 12 issues a warning on the fortify strncat wrapper might overflow the destination buffer (the failure is tied to -Werror). Checked on ppc64 and x86_64. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>
