Made scalebox the way sway does it

Browse source 
Scaling a wlr_box without rounding can sometimes make the borders not
connected and nice. I noticed this when setting scale in monrules to 1.2

So I've went and copied what Sway did in desktop/output.c but without
having a second function and now using a random rounding macro I found
on the internet so as to not use round from math.h.
