Arrow keys don't appear to work

[Restioson]

Tested in qemu with following code:

loop {
    if let Ok(Some(event)) = keyboard.read_event() {
        if event.event_type == KeyEventType::Break &&
            event.keycode == keymap::codes::DOWN_ARROW
        {
                break;
        }
    }
}

This is unrelated to the fact that arrow keys do not cause the cursor to move. Imo since the 'prompt' is just for fun and to showcase we don't need to make it to complicated/support arrow keys.

@gegy1000 could you verify that it works in the ps2 rework?
