efl_ui_focus_graph: improve results based on lvls
This improves the results from the graph calculations. Everything is documented in the comments. The genlist of focus 6 is placed in a way that the button at the top is not in reach, before we only had lvl1 and lvl2 (as described in the code comment), thus the button was only reachable via right not via top. lvl3 makes it accessable via top AND right. fix T7098 Differential Revision: https://phab.enlightenment.org/D6491
