* command-stubs/pump-stub: Removed (#239427).

        * command-stubs/dhcpclient-stub: Wrote new command to provide an IPv4
        and IPv6 dhcp/auto client at the command line in rescue mode (#239427).
        * scripts/upd-instroot: Install dhcpclient-stub, symlink /usr/bin/pump
        to /usr/bin/dhcpclient (#239427).
