Don't make W32 code conditional on HAVE_SOCKETS, it's always defined.

* w32.c: Remove top-level uses of #ifdef HAVE_SOCKETS.
  (gethostname) [!HAVE_SOCKETS]: Remove.
  (SOCK_REPLACE_HANDLE): Remove macro.
  (socket_to_fd, sys_close, _sys_read_ahead, sys_read, sys_write)
  (term_ntproc, init_ntproc): Don't conditionalize on HAVE_SOCKETS.
* w32proc.c: Remove top-level uses of #ifdef HAVE_SOCKETS.
  (syms_of_ntproc): Don't conditionalize on HAVE_SOCKETS.
