Update some test capture files

Update some test capture files

These changes avoid some pcap_loop() errors messages like:
"tcpdump: pcap_loop: invalid packet capture length X, bigger than
snaplen of Y"
or
"tcpdump: pcap_loop: truncated dump file; tried to read X captured
bytes, only got Y"

The outputs of the tests are unchanged.

Remove the no more useful -c options in the test configurations.
