pimd: Show interface traffic even if interface is currently `down`

the `show ip pim interface [x] traffic` command was deciding
to skip display of interfaces if they happened to be down at
that moment.  This of course does not make a bunch of sense
to limit the output for a interface that may have sent data
in the past.

This fixes this test crash:
rnode = <lib.topogen.TopoRouter object at 0x7fc755be3880>, dut = 'c1', input_dict = {'c1': {'c1-l1-eth2': ['helloTx', 'helloRx']}}, output_dict = {'c1': {}}

    def show_pim_intf_traffic(rnode, dut, input_dict, output_dict):
        show_pim_intf_traffic_json = run_frr_cmd(
            rnode, "show ip pim interface traffic json", isjson=True
        )

        output_dict[dut] = {}
        for intf, data in input_dict[dut].items():
>           interface_json = show_pim_intf_traffic_json[intf]
E           KeyError: 'c1-l1-eth2'
