KEYS: Fix for erroneous trust of incorrectly signed X.509 certs
Arbitrary X.509 certificates without authority key identifiers (AKIs) can be added to "trusted" keyrings, including IMA or EVM certs loaded from the filesystem. Signature verification is currently bypassed for certs without AKIs. Trusted keys were recently refactored, and this bug is not present in 4.6. restrict_link_by_signature should return -ENOKEY (no matching parent certificate found) if the certificate being evaluated has no AKIs, instead of bypassing signature checks and returning 0 (new certificate accepted).
