Subject: [PATCH 3/4] 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>

(cherry picked from commit f1c7ed0859a45929136836341741c7cd70f428cb)
