openpgp: support creating signatures compatible with 'gpg --sign'.

This is neither a '--clearsign' nor a '--detach-sign' which are already
supported.  Verification of these signatures is already supported by
ReadMessage.

The code shares a lot with standard encrypt/sign, so mostly a
refactoring of 'Encrypt' to allow use of the code path without
actually doing a signing.
