stdlib: Fix __getrandom_nocancel type and arc4random usage (BZ #29638)
Using an unsigned type prevents the fallback to be used if kernel
does not support getrandom syscall.
Checked on x86_64-linux-gnu.
Reviewed-by: Wilco Dijkstra <Wilco.Dijkstra@arm.com>
(cherry picked from commit 13db9ee2cb3b77e25f852be7d6952882e1be6f00)
