futility: preserve preamble flags when resigning BIOS images

If we're re-signing a valid BIOS image, we want to be sure that
we preserve the original firmware preamble flags (RO_NORMAL and
so forth) if the --flags option does not specifically override
it.

This change adds a test for that case, and makes it happen.
