packets: create new compose_lacp_pdu() function.

Creates new compose_lacp_pdu() from the old compose_lacp_packet()
function.  This will allow a LACP PDU to be created without
necessarily knowing the Ethernet Source Address required for
generating the packet.  Future patches rely on this functionality.
