lldp: add sd_lldp_tlv_packet_get_destination_type()
It can be useful to know the destination address of a LLDP frame
because it determines the scope of propagation of the frame and thus
this information be used to know whether the neighbor is connected to
the same physical link.
See clause 7.1 of IEEE Std 802.1AB-2009.
