[PATCH v3 5/9] lsm: security: Add additional enum values for bpf integrity checks

[Blaise Boscaccy]

First add a generic LSM_INT_VERDICT_FAULT value to indicate a system
failure during checking. Second, add a LSM_INT_VERDICT_UNKNOWNKEY to
signal that the payload was signed with a key other than one that
exists in the secondary keyring. And finally add an
LSM_INT_VERDICT_UNEXPECTED enum value to indicate that a unexpected
hash value was encountered at some stage of verification.
