futility gscvd: add option to print out root key hash
The root public key hash needs to be incorporated into the GSC
firmware. Before this patch the only way to get the hash was to
preform an AP RO firmware signing operation, which, among other things
requires access to the platform private key.
This patch adds another invocation option where only the -r parameter
is passed in, in which case the hash of the public key is printed.
