    http2/vtc: Stabilize WR_SHUT test
    
    If a shutdown command is last in the vtc client, it closes the file descriptor
    right after the shutdown, such that varnishd can not reliably send the GOAWAY,
    which in turn changes the H2 error message.
    
    Ref #4283
    Ref #4284
    Closes #4293
