Story time: In the days of yore, we generated PCAPs using tcpdump, which will flush any buffered packets to its output file on reception of SIGUSR2. Therefore we sent a USR2 before terminating the capture. At some point, we switched over to use tshark to capture packets for us, but the SIGUSR2 sayed in place. It turns out, tshark will just die on USR2, abandoning the dumpcap child it has created, which means the enclosing network namespace can't be properly torn down. Therefore: Remove skip sending USR2 and just send TERM directly.
