The driver programs are useful in quick and dirty fuzz testing of the verification code with blind smartfuzzers like Bunny (http://code.google.com/p/bunny-the-fuzzer/). Also fixes a bug with image generation in kernel_utility. Tests: All existing tests still pass. VerifyKernel() and VerifyFirmware() can successfully verify images generated by {firmware|kernel}_utility. Review URL: http://codereview.chromium.org/975007
