Bug#1005058: dnsperf: python3/-pcapy dependencies

[Bastian Germann]

Package: dnsperf
Version: 2.9.0-1

dnsperf's pcap-queryparse depends on python3 and python3-pcapy. Please make them dependencies (which is also hinted by 
the lintian error), remove that binary from the package, or create an additional binary package from it (if you want to 
keep the possibility to install the dnsperf package without the python3 dependency).
