[PATCH] stdlib: Tuned down tst-arc4random-thread internal parameters

Doesn't this make outer_threads on many systems?

By the way, I think we should switch to the standard arc4random_uniform
implementation that doesn't try to conserve bits.  It's cheaper to get a
larger number of bits once instead of obtaining 24 bits first, then 8
bits.

Thanks,
