Fix test suite deficiencies.

While trying to debug/test some vbutil_kernel changes
(coming in a different CL) it was noticed that this utility
is not covered by tests, and the script which runs it to set
up further testing (tests/gen_fuzz_test_cases.sh) fails
because of the key format mismatch.

Some investigation has shown that this was left behind when
vboot_reference key storage format was changed.

To make gen_fuzz_test_cases.sh work again a new set of test
keys is required, the keys are generated by
tests/gen_test_keys.sh. This utility had to be changed to
generate the proper set of wrapped public and private keys.

Actually code in tests/gen_test_keys.shgenerate_keys() is
copied in pasted in many scripts in this tree, this has to
be refactored, but under a different CL.

Once the changes were made, two scripts were run:
 ./tests/gen_test_keys.sh
 ./gen_test_cases.sh

resulting in the new and updated keys generated.

firmware/stub/tpm_lite_stub.c was edited to fix compilation
warning issued when compiling with debugging enabled.

BUG=chromium-os:7178
TEST=described below

The following commands succeed:

vvvvvvvvvvvvvvvvvvvvvvvvvvvvvvv
make
make runtests
./tests/gen_fuzz_test_cases.sh
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

note that  ./tests/gen_fuzz_test_cases.sh was failing
before this change.

The upcoming CL modifying vbutil_kernel will make sure
gen_fuzz_test_cases.sh is executed when tests are run and
will enhance it to cover vbutil_kernel testing.
