Windows msys2 + mingw64, openssl 3.1 : warnings in apps/lib/s_socket.c

warnings:

apps/lib/s_socket.c:141:25: warning: overflow in conversion from 'long long unsigned int' to 'int' changes value from '18446744073709551615' to '-1' [-Woverflo
]
  141 |                 *sock = INVALID_SOCKET;
      |                         ^~~~~~~~~~~~~~
apps/lib/s_socket.c:167:21: warning: overflow in conversion from 'long long unsigned int' to 'int' changes value from '18446744073709551615' to '-1' [-Woverflo
]
  167 |             *sock = INVALID_SOCKET;
      |                     ^~~~~~~~~~~~~~

indeed, on Windows, SOCKET is defined as typedef UINT_PTR SOCKET; and INVALID_SOCKET is defined as #define INVALID_SOCKET (SOCKET)(~0), while *sock is an int

Start in apps/lib/s_socket.c at lines 141 and 167, then inspect the Windows SOCKET and INVALID_SOCKET definitions involved in assigning to *sock. Confirm the fix by rebuilding the affected Windows msys2/mingw64 configuration and verifying that these overflow warnings no longer appear.
