clone: for local clones, copy over filtered branchcaches as well (issue4286) Local clones copy/hardlink over files directly, so the branchcaches should all be valid. There's a slight chance that a read operation would update one of the branchcaches, but we hold a lock over the source repo so they shouldn't cause an invalid branchcache to be copied over, just a different, valid one.
