rootfs.py: Respect OPKGLIBDIR variable

* when OPKGLIBDIR doesn't have the default /var/lib value it will
  silently fail to copy package database from normal rootfs to debugfs
  rootfs and then when trying to install *-dbg complimentary packages
  it won't install anything, because installed_pkgs.txt file generated
  from debugfs is empty
