    arch/sim: Set idle thread stack size to zero
    
    to avoid ps generate "Segmentation fault" because do_stackcheck
    check the stack color if the stack size doesn't equal zero
    BTW, it is better to set idle task stack size to zero since idle
    task use the host thread and the stack size from config isn't the
    actual value.
