Bill Richardson 82db93d5fc futility: Add show capability for usbpd1 images ...

The firmware for the USB Type-C power adapters uses raw binary
blobs for the public keys and signatures instead of
readily-identifiable structs. We've been able to sign these
firmware images for some time, but verifying the result generally
required testing them on hardware.

This CL adds some futilty support for recognizing and verifying
those images too. It just tries various sig and hash algorithms,
until it finds a combination for which the image is
self-consistent (where the pubkey blob verifies the signature
blob).

BUG=none
BRANCH=none
TEST=make runtests

This change also adds additional tests for usbpd1 images. We
ensure that we correctly recognize and verify an MP-signed
firmware, plus test signing and verifying usbpd1 images using
multiple signature and hash algorithms.
