libpayload/cbgfx: Fix overflow in transform_vector()
Fix potential overflow when multiplying integers in transform_vector().
This issue is causing the absolute coordinate of the bottom right corner
of the box to be incorrectly calculated for draw_rounded_box(), which is
used in menu UI to clear the previous screen.
In addition, check the lower bound in within_box().
