    sshdump: Change ws_close to closesocket

    ws_close just calls _close(); that doesn't close sockets.  closesocket()
    is the API to close a socket on Windows, and is defined as close()
    on UN*X, so using closesocket() will close sockets on Windows and UN*X.

    This way, we close the pipe socket correctly on Windows.
