[git commit] use [s]rand(), not [s]random()

[Denys Vlasenko]

commit: http://git.busybox.net/busybox/commit/?id=0ed5f7aacd5e412d80524a1fc7f90b55f470827b
branch: http://git.busybox.net/busybox/commit/?id=refs/heads/master

rand() is the most standard C library function,
and on uclibc they are the same. I guess
they are the same in most todays' libc...
