stream-clone: disable gc for the entry listing section for the v2 format
This is similar to the change we did for the v3 format in 6e4c8366c5ce.
The benchmark bellow show this gives us a notable gains, especially on larger
repositories.

====================================
Testing head checking code: Case B-2
====================================
Mercurial checks for the introduction of new heads on push. Evolution comes
into play to detect if existing branches on the server are being replaced by
some of the new one we push.
This case is part of a series of tests checking this behavior.
Category B: simple case involving pruned changesets
TestCase 2: multi-changeset branch, head is pruned, rest is superseded
.. old-state:
..
.. * 2 changeset branch
..
.. new-state:
..
.. * old head is pruned
.. * 1 new branch succeeding to the other changeset in the old branch
..
.. expected-result:
..
.. * push allowed
