opkg: solve inconsistency of using different lists directories

Default behavior of opkg was to use ${OPKGLIBDIR}/opkg/lists;
but in our recipe we modify it to ${OPKGLIBDIR}/opkg/${OPKGLIBDIR}/opkg/,
when appending package-management to IMAGE_FEATURES these lists are
populated during build time (using the default directory),
but since our config was different these populated lists were never used at runtime, this patch solves this inconsistency by using default behavior for both build time and runtime.
