wininet: Include <unistd.h> in case we need off_t for zlib.

    wininet: Always use winsock sockets.

FreeBSD not longer builds due to the following change:

   #include "config.h"
  -#include "wine/port.h"
 
  -#if defined(__MINGW32__) || defined (_MSC_VER)
  -#include <ws2tcpip.h>
  +#ifdef HAVE_ZLIB
  +#  define Z_SOLO
  +#  include <zlib.h>
   #endif

zlib.h on FreeBSD 10.x uses off_t, but at this point this is not
defined yet.  Including unistd.h before including zlib.h addresses
this.
