CVE-2018-20552,CVE-2018-20553,tcpreplay: no-dsa for Jessie

The heap-based buffer overflows are reproducible with ASAN, without ASAN the
tcprep tool segfaults. Since we have marked similar issues as no-dsa in the
past and none of our sponsors uses it, I also mark it as no-dsa. In addition to
exploit this issue one has to manipulate a pcap file and trick someone into
using it.
