pcap handles are not thread safe
...
they contain an errbuf; there might be other issues too.
So we must use different handles in the sniffer and udplistener
goroutines.

capture and inject on the same pcap handle
...
...since there's no need to have separate handles
Also, make router.Start() perform all startup, including starting a
sniffer goroutine. The main goroutine is now kept alive by the signal
handling loop.
