Add random seed to run-tests.py, using either a user supplied value or a random number generated by random.SystemRandom(). This same random seed is passed to all test cases, making sure that we can easily reproduce test failures that depend on random numbers (i.e. bugs related to our handwritten ASLR). Also fix all uses of rand() to make use of our RNG class instead.
