Mickaël Salaün 58d416351e tools/certs: Add print-cert-tbs-hash.sh
Add a new helper print-cert-tbs-hash.sh to generate a TBSCertificate
hash from a given certificate.  This is useful to generate a blacklist
key description used to forbid loading a specific certificate in a
keyring, or to invalidate a certificate provided by a PKCS#7 file.

This kind of hash formatting is required to populate the file pointed
out by CONFIG_SYSTEM_BLACKLIST_HASH_LIST, but only the kernel code was
available to understand how to effectively create such hash.
