pkcs7: fix check for self-signed certificate
pkcs7_validate_trust_one() used 'x509->next == x509' to identify a
self-signed certificate. That's wrong; ->next is simply the link in the
linked list of certificates in the PKCS#7 message. It should be
checking ->signer instead. Fix it.
Fortunately this didn't actually matter because when we re-visited
'x509' on the next iteration via 'x509->signer', it was already seen and
not verified, so we returned -ENOKEY anyway.
