These are slightly more complex than the firmware versions, because
they need to deal with developer-signed keyblocks and keyblock flags.

This also checks that the bootloader and vmlinuz headers, if present,
are within the signed part of the kernel blob; the vboot1 routines
didn't do that. That wasn't harmful at firmware boot time because the
vboot1 routines would only load as much data as was signed, but in
vboot2 loading the kernel data is the responsibility of the caller so
we need to check.
