treewide: use get_random_u32_inclusive() when possible
These cases were done with this Coccinelle:

expression H;
expression L;

- (get_random_u32_below(H) + L)
+ get_random_u32_inclusive(L, H + L - 1)

And then subsequently cleaned up by hand, with several automatic cases
rejected if it didn't make sense contextually.
