If we have "pcap_datalink_val_to_name()", use it when we construct a

"-y" argument for the capture subprocess - the capture subprocess will
expect a symbolic value, not a numeric value, if we have
"pcap_datalink_name_to_val()".  (We assume that if one is present the
other will be present as well.)
