In CL:378661 we removed dev_firmware* from tests/devkey but that also makes
futility unit tests to fail.
This changes signing test scripts to first check if dev_firmware* keys exist,
and only use it (and test ZGB signing results) if available.
BRANCH=none
BUG=chrome-os-partner:52568,chrome-os-partner:56917
TEST=make runfutiltests; make runtests;
add dev_firmware* back; run tests again and success.
