openpgp: Store the issuer key id and fingerprint in <openpgp-signature>.
* guix/openpgp.scm (<openpgp-signature>)[issuer, issuer-fingerprint]: New fields. (openpgp-signature-issuer, openpgp-signature-issuer-fingerprint): Remove. (verify-openpgp-signature): Use 'openpgp-signature-issuer-key-id'. (get-signature): Initialize 'issuer' and 'issuer-fingerprint'. * tests/openpgp.scm ("get-openpgp-detached-signature/ascii"): Adjust accordingly.
