If trusted-keys() is used, the certificate fingerprint is added added
to ${.tls.x509_fp} with the same algorithm that was used to validate
trusted-keys, which is SHA1 at the moment (unfortunately, but that's
a separate PR.

I've dropped the change in trusted-keys() validation, as we agreed with @MrAnno that it should be introduced with a new option (trusted-fingerprints() or something like that).

By dropping this patch, this PR became very simple, if there's trusted-keys() based validation in a config, the key fingerprint is saved into ${.tls.x509_fp} along with the CA and similar parameters.

With that this is mergable.
