btrfsutil: Rename unexported types to be clearer about which system they belong to

 - nodeInfo    → oldRebuiltNodeInfo (old_rebuilt_forrest.go)
 - itemStats   → rebuiltItemStats   (rebuilt_tree.go)
 - rootStats   → rebuiltRootStats   (rebuilt_tree.go)
 - nodeScanner → nodeLister         (listnodes.go)
 - nodeStats   → nodeListStats      (listnodes.go)
 - scanStats   → devScanStats       (scan.go)
