  -----------
  [libc++] Refactor the tests for std::random_device

That will make it easier to change the behavior of the arc4random()
based implementation. Note that in particular, the eval.pass.cpp test
used to work with non "/dev/random" based implementations because we'd
throw an exception upon constructing the random_device. This patch makes
the intent of the test clearer.
