We have three copies of the same pseudo random number generator in our test codes. Let's consolidate them into a single copy in test_util. BUG=chrome-os-partner:19235 TEST=Pass all tests BRANCH=None Change-Id: I7ea0b3476f3cfe6944855f19861e3c86af35807e Signed-off-by: Vic (Chun-Ju) Yang <victoryang@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/181085 Reviewed-by: Vincent Palatin <vpalatin@chromium.org>
