Bug fix: Only create TLS key with certtool, and read correct key file

* debian/mandos-client.postinst (create_keys): Remove any bad keys
                                               created by 1.8.0-1.
                                               Only create TLS keys if
                                               certtool succeeds.
* debian/mandos.postinst (configure): Remove any bad keys from
                                      clients.conf, and inform the
                                      user if any were found.
* debian/mandos.templates (mandos/removed_bad_key_ids): New message.
* mandos (MandosServer.handle_ipc): Do not trust a key_id with a known
                                    bad key ID.
* mandos-keygen (keygen): Only create TLS keys if certtool succeeds.
  (password): Bug fix: Generate key_id correctly, and only output
              key_id if TLS key exists.
