Remove signature-based vboot support
Superseded by EC software sync (hash-based).
Sig-based vboot was correctly implemented, but ended up being too slow
to be useful given the limited processing power of the EC chips, and
we also couldn't come up with a manageable way to handle A/B
autoupdate of signed EC firmware.
This change and an associated vboot_reference change shrinks the EC
binary by ~2KB.
BUG=chrome-os-partner:11232
TEST=build link,snow; boot link and check that 'hash' command still works.
