gen_fuzz_test_cases.sh is the only file that is a part of this. It picked up the
other changes too since they haven't been pushed in yet. I will clean-up the
patch before commit it though.

Clean ups.

With no --flags, LoadKernel() should reject the key block since it won't match
the current boot mode.

Pass --flags=15 to make a key block which works in any mode.

actually, this whole function was left here by mistake. Removed.
