[PATCH ARM v7 03/13] mini-os: move poor rand function to test.c

[Thomas Leonard <talex5@gmail.com>]

It's only used by test.c and probably isn't something that should be
exposed for general use (it just calls gettimeofday).

This is also useful for ARM, which doesn't use math.c, where this used
to live.
