rootfs.py: fix uninstall uneeded pkgs failed

The refactor of shell function rootfs_uninstall_unneeded is incorrect,
it should check and update the installed_pkgs.txt file for the existance
of the packages that were removed.

            # update-rc.d, base-passwd, run-postinsts are no further
            # use, remove them now
            remove_run_postinsts=false
            if [ -e ${IMAGE_ROOTFS}${sysconfdir}/init.d/run-postinsts ]; then
