bundle2: introduce `replycaps` part for on-demand reply

The bundle2 processing does not create a bundle2 reply by default anymore.  It
is only done if the client requests it with a `replycaps` part. This part is
called `replycaps` as it will eventually contain data about which bundle2
capabilities are supported by the client.

We have to add a flag to the test command to control whether a reply is
generated or not.
