    androiddump: Fix non-blocking connect on Windows
    
    Commit 043ed1f6 enabled non-blocking connect on Windows. This seems to
    break androiddump on Windows completely, since a successful connection
    always returns SOCKET_ERROR on connect, with WSAGetLastError() set to
    WSAEWOULDBLOCK.
    
    Apparently, the only way to check for a real connection is to try a
    write select on the socket:

    This fixes androiddump on Windows:
    - If ADB server is running, extcap interfaces are listed
    - If ADB is not running, there is no noticeable delay in Wireshark
