util/box: Calculation error of wlr_box_closest_point in multi-screen mode

Browse source 
In multi-screen mode, when the mouse is on the first screen (default
position (100,100)), when the first mask is removed, box is (1920,0).
If you directly assign *dest_x = box->x, the mouse position on the
second screen will become (1920,100), which is wrong. When x < box->x,
x should also be added to box, and y should be the same.
