Support authentication of uefi priv. variables
To authenticate private uefi variables a fingerprint has to be
calculated based on the common name of the signing certificate's
Subject field and the tbsCertificate of the top-level issuer
certificate.
These variables have a public key certificate attached so the
verify_pkcs7_signature_handler is also reorganized to be able
to verify its own signature with its internal public key.
This commit implements the changes needed for the described
functionality.
