oox smartart: fix crash in pyra algorithm with a single child shape

Regression from commit 14a56533ff2c9c859d22cd3039ada75b99e94bc0
(SmartArt Pyramid: Now lays out shapes, 2018-07-10), the added pyramid
algorithm by first centering the topmost children, then decrementing the
horizontal postion of each additional shape, with the end goal of having
0 horizontal position of the last children.

This means that simply avoiding the division in the 1-child case leads
to correct results, because in this case the only child is also the last
child at the sane time.
