win32: fix building with NO_UNIX_SOCKETS

After 2406bf5f (Win32: detect unix socket support at runtime,
2024-04-03), it fails with:

compat/mingw.c:4160:5: error: no previous prototype for function 'mingw_have_unix_sockets' [-Werror,-Wmissing-prototypes]
   4160 | int mingw_have_unix_sockets(void)
        |     ^

because the prototype is behind `ifndef NO_UNIX_SOCKETS`.
