Arch Linux -4 patch

Forum member noryb009 sent me another patch for Arch Linux support in Woof. Quoting the pm:

This is a small patch to speed up arch linux in 0setup, along with a sorting fix.

- make the awk command get the category and path (doesn't need to be parsed the second time), which speeds up the script a bit.
- removes using the sort command, ls already sorts the folders by name
