rescue: Move files around and introduce proper dep tracking.
This moves any perl files into bin and sbin folders which will be directly installed in /usr/bin and /usr/sbin. This is done such that the extract modes in list.xml still work and the files end up in the right places. All other files have been moved into the tree folder in their final destination.
