    Test for DANE cross cert fix

commit 661de442e4231a9b0411dc8562f9e465d1d7fabc
Author: Viktor Dukhovni <openssl-users at dukhovni.org>
Date:   Mon Aug 30 14:17:16 2021 -0400

    Prioritise DANE TLSA issuer certs over peer certs
    
    When building the certificate chain, prioritise any Cert(0) Full(0)
    certificates from TLSA records over certificates received from the peer.
    
    This is important when the server sends a cross cert, but TLSA records include
    the underlying root CA cert.  We want to construct a chain with the issuer from
    the TLSA record, which can then match the TLSA records (while the associated
    cross cert may not).
