Add Cybertrust Japan's iTrust Root CA

This case requests inclusion of Cybertrust Japan’s iTrust Root CA in Mozilla’s trust program with the email trust bit enabled. The request is tied to CCADB Root Inclusion Case #975. During the discussion, Mozilla staff noted that a Value Statement and a sample S/MIME client certificate that chains to the root would be needed, and referenced a companion CCADB request for CAs with the websites bit enabled. The thread later states that CCADB Root Inclusion Case #975 was closed and that this bug could be closed as well. The bug’s resolution is WONTFIX, and the thread clarifies that the intended use of the Cybertrust iTrust Root CA is to support MS and Adobe Document Signing rather than S/MIME/email.
