    libxl: spawn: Always debug log middle child process death
    
    Otherwise the debug log is strangely devoid of an explanation for the
    spawn completing.
    
    We decorate `what', as otherwise the logged message is rather alarming
    (especially if the death is due to us sending SIGKILL, which even
    happens on the success path).
