stream-clone: also filter the requirement we put in the bundle 2

We were wrongly putting irrelevant requirements in the bundle and the receiving
side was getting confused, treating them as being missing while still putting
them in the `requires` file. Leading do corrupted repositories.

This changes fix stream-clone behavior regarding format when bundle-2 is
involved, so we now also test this cases.

Behavior with older version of Mercurial will be fine as they filter the
requirements they get from the bundle on their side anyway.
