lib:replace: Do not build strndup test with gcc 11 or newer
BUG: https://bugzilla.samba.org/show_bug.cgi?id=14699
gcc11 with -O3 detects that the size is incorrect:
lib/replace/tests/testsuite.c:286:13: error: ‘strndup’ specified bound 10 exceeds source size 4 [-Werror=stringop-overread]
286 | x = strndup("bla", 10);
| ^~~~~~~~~~~~~~~~~~
