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.
...
rootfs_uninstall_unneeded () {
    if ${@base_contains("IMAGE_FEATURES", "package-management", "false", "true", d)}; then
        if [ -z "$(delayed_postinsts)" ]; then
            # All packages were successfully configured.
            # 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
                remove_run_postinsts=true
            fi

            # Remove package only if it's installed
            pkgs_to_remove="update-rc.d base-passwd ${ROOTFS_BOOTSTRAP_INSTALL}"
            for pkg in $pkgs_to_remove; do
                # regexp for pkg, to be used in grep and sed
                pkg_regexp="^`echo $pkg | sed 's/\./\\\./'` "
                if grep -q "$pkg_regexp" ${WORKDIR}/installed_pkgs.txt; then
                rootfs_uninstall_packages $pkg
                sed -i "/$pkg_regexp/d" ${WORKDIR}/installed_pkgs.txt
                fi
