[PATCH] libpcap: Add datalink-type to match IEEE 802.15.4 ARP hardware type

Since Linux 2.6.30, IEEE 802.15.4 interfaces got assigned a proper ARP hardware type (ARPHRD_IEEE802154 - 804). This patch introduces the relevant code to match it with its own DLT type. There are currently three different types for it, but DLT_IEEE802_15_4 is the safest standard choice.
