fix(infra): strip the ansible.builtin. prefix without strlen on the offset

GCC 13 on x86-64 (-O1, ASan/UBSan, -Werror) rejected an_key's memmove(out, out + bl, strlen(out + bl) + 1) as -Wstringop-overread, a region of size 0; arm64 GCC and clang accept it. The key length is now measured once and the prefix compared with memcmp. Every C file this branch changes compiles warning-free with that GCC.
