clone: copy obsolete marker on local clone

This change add `obsstore` to the list of files copied during clone. Before this
changeset, extinct changeset were copied without their related obsolete marker.

Note: extinct changesets were included by such clone prior to this changeset.
This is still the case now. There is no strong requirement to exclude obsolete
changesets from the clone as long as they remains obsolete after push. Doing so
allows to use hard link clone even if obsolete changesets exist on the source.
