[docker-ptf]: Added python-libpcap for the updated arp responder (#3731)

Added python-libpcap to be used by arp_responder.py utility. This is needed to set conf.use_pcap which will make sure that L2pcapListenSocket uses libpcap instead of Linux PF_PACKET sockets. By using libpcap the vlan field will not be removed when the application receives the packet.
