cdfae7d453 apps/maze: fix possible stack overflow 
The original code this app is inspired from uses rand(), which returns
a number >= 0.
mulberry32() on the other hand can return a negative number, in which
case will overflow the accesses in the dirs array. Fix that by forcing
the result to be unsigned.
