make test: work around scapy truncated packets
Under stress, it's possible to hit a race condition, when the packet
header is fully written to pcap, but not all packet data - yet.
Scapy is stupid enough to:
1. not detect and report this error, truncating the packet instead
2. continue munching more data from wrong offset
The work around is to scan the file ahead, parse the packet header,
figure out how much data we need, wait for the file to be big
enough, then restore the file position back to where it was
and finally let scapy parse the packet.
