Revert of Include unverified server-sent cert chain in reports

Revert of Include unverified server-sent cert chain in reports (patchset #2 id:20001 of https://codereview.chromium.org/1180313006/)

Reason for revert:
Appears this breaks CertificateErrorReportTest.SerializedReportAsProtobuf.

Original issue's description:
> Include unverified server-sent cert chain in reports
>
> As of https://codereview.chromium.org/1174073003/, net::SSLInfo contains
> the unverified certificate chain as received by the client (which might
> be different than the chain as built by the client during
> verification). This CL adds the unverified chain to invalid certificate
> reports.
