DKIM-sign Content-Type and oversign all signed headers

Oversigning (including header name in DKIM-Signature
more times that it appears in the mail) prevents
adding more headers with the same name
without invalidating DKIM signature.

We don't want middleboxes to insert a second From header,
adding Cc field to mails that don't have one etc.
