openpgp: Fix primary key flags handling.
- Previously, we implicitly set the certification flag when we
created subkeys. However, certification is about certifying other
keys and (key, userid)-bindings, it has nothing to do with the
primary key's ability to bind components together.
- By default, the primary key is marked as certification-capable,
but the user should be able to override this, including removing
the certification-capability.
