stream-clone: check is a compatible protocol can be found

The previous code was explicitly checking if "v2" is listed in the "stream"
bundle2 capability. The new code is checking is there is anything common
between the versions supported client side and server side overlaps.

This prepare the introduction of more stream version than "v2".
