target: Don't symlink outside of /var
We will want to share /var with petitboot plugins, but most of the
directories in /var are actually symlinks to outside of var (to /tmp).
This change replaces the symlinks with actual directories. Since we're
running in an initramfs, we don't need to put everything in /tmp.
