Add OpenSSL patch to include <sys/stat.h> in s_server.c

- Introduced a check in build-libraries.sh to add the <sys/stat.h> include directive to apps/s_server.c if it is missing.
- This patch ensures compatibility with systems that require this header for proper functionality of the OpenSSL s_server application.
