    openssl s_server: don't use sendto() with connected UDP socket
    
    Fixes #7675
    
    On macOS, if you call `connect()` on a UDP socket you cannot then
    call `sendto()` with a destination, otherwise it fails with Err#56
    ('socket is already connected').
    
    By calling `BIO_ctrl_set_connected()` on the wbio we can tell it
    that the socket has been connected and make it call `send()` rather
    than `sendto()`.
