ipk: use OPKGLIBDIR in all places

* it's not recommended to change this value, because it breaks upgrade path on target
  (all old u-a alternatives are forgot in old OPKGLIBDIR value
* but make it consistent, so if someone really want to change that, then
  setting OPKGLIBDIR_distro in distro.conf would be enough
* without this there were at least 4 places to change:
  rootfs_ipk: opkglibdir variable (notice that I've removed /opkg from it to correspond
              with EXTRA_OECONF option used in opkg recipes
  package_ipk: ${target_rootfs}${localstatedir}/lib/opkg/ hardcoded in
               package_install_internal_ipk
  opkg-collateral: value in lists file
  opkg: EXTRA_OECONF for all 3 classes, FILES_libopkg, do_install
* validated with buildhistory that without OPKGLIBDIR explicitly set the
  output is the same and that after setting
  OPKGLIBDIR_forcevariable := "${libdir}"
  everything including empty directory from package_ipk is moved to
  libdir
