bundle2: handle compression in _forwardchunks

_forwardchunks is used to compensate for getbundle protocol deficits.
Since it transparently decodes the payload, it also needs to remove the
corresponding compression parameter in case the server decides to send
one. This the wire protocol part of issue 5990.
