certs: Make blacklist_vet_description() more strict
Before exposing this new key type to user space, make sure that only
meaningful blacklisted hashes are accepted. This is also checked for
builtin blacklisted hashes, but a following commit make sure that the
user will notice (at built time) and will fix the configuration if it
already included errors.
Check that a blacklist key description starts with a valid prefix and
then a valid hexadecimal string.
