bump libnDPI to 6b7e5fa8d251f11c1bae16ea892a43a92b098480

 * fixed linking issue by using CMake to check if explicit link against libm required
 * make nDPIsrvd collectd exit if parent pid changed, meaning that collectd died somehow
 * nDPId-test restores SIGPIPE to the default handler (termination), so abnormal connection drop's do now have consequences
