refind: enable page_poison by default, rewrite hook

- both efibootmgr and grub enable page_poison by default.
  Let's enable it with refind, too
- The old post-install hook was written (by me, myself)
  was originally written in ed, and converted to ugly-and-lengthy
  while-read-echo sh.
  Both base-minimal, base-system, and base-chroot provides some kind
  of awk, let's rewrite it in awk.
