D25363: Fix one more buffer overread in ksysguard network helper

  I wonder whether this can actually happen, as that header is AFAICT added by the kernel and not from the network.
  
  The `Packet` constructor has both `dataLength` and `packetSize` parameters, which are equal to the pcap header's `caplen` and `len`, respectively, and only the former specifies how much data is actually available in the buffer.
  So the comparison has to use `dataLength`, like the code below.
