x509: corrected issue in the algorithm parameters comparisontmp-fix-cert-params-checks

Each certificate has two fields to set the signature algorithm
and parameters used for the digital signature. One of the fields is
authenticated and the other is not. It is required from RFC5280 to
enforce the equality of these fields, but currently due to an issue
we wouldn't enforce the equality of the parameters fields. This
fix corrects the issue.

We also move an RSA-PSS certificate in chainverify that was relying
on invalid parameters, to this set of invalid certificates.

Resolves: #698
