    ping6: treat setsockopt failures as fatal
    
    ping6 needs IPV6_RECVPKTINFO and IPV6_RECVHOPLIMIT to process
    incoming replies. When these options fail, replies are silently
    dropped and ping6 appears to hang. Use err(3) instead of warn(3)
    so the user gets a clear error and immediate exit.
