bitbake: knotty: Enforce terminal line limit to stop crazy scrolling
If there are more tasks running than there are lines on the terminal, the data scrolls in ways the UI wasn't designed for. This patch adjusts the UI just to show the processes which fit onto the number of rows in the terminal window. You can see the total number running from the counter in the top left as usual and this makes warning and errors messages scrolling from the top of the window work as designed. Ultimately, scrolling would be nice but is for another time, this fixes the biggest UI issue on highly parallel machines.
