pcap: let netsniff-ng also record pkt timestamp source
With commit [1] in the kernel, we can also store the timestamp source in the pcap packet header for later analysis. We do this by splitting the netsniff-ng's u32 ifindex into u16 tsource and u16 ifindex. Older kernel do not support the timestamp source in PF_PACKET, so it will stay 0 and is compatible with older netsniff-ng binaries.
