    crypto/tls: fix client certificates support for legacy servers · d8ce141d
    Filippo Valsorda authored
    signatureSchemesForCertificate was written to be used with TLS 1.3, but
    ended up used for TLS 1.2 client certificates in a refactor. Since it
    only supported TLS 1.3 signature algorithms, it would lead to no RSA
    client certificates being sent to servers that didn't support RSA-PSS.
    
    TestHandshakeClientCertRSAPKCS1v15 was testing *specifically* for this,
    but alas the OpenSSL flag -verify accepts an empty certificates list as
    valid, as opposed to -Verify...
    
    Fixes #28925
