parted: Update LFS to reflect that parted is no longer an addon

- In 2018 parted was moved from being an addon to being a core program
- The rootfile was moved from rootfiles/packages/ to rootfiles/common/
- The LFS was not updated to remove the PAK_VER etc elements.
- This patch adjusts the LFS file to be in line with being a core program
