kdc: remove KRB5SignedPath, to be replaced with PAC

KRB5SignedPath was a Heimdal-specific authorization data element used to
protect the authenticity of evidence tickets when used in constrained
delegation (without a Windows PAC).

Remove this, to be replaced with the Windows PAC which itself now supports
signing the entire ticket in the TGS key.
