nc (netcat): don't block when run interactively

Browse source 
When running the test suite interactively, "Connect to pod
hostport from the host" test hangs because nc thinks it's
got a bidirectional connection. Running with </dev/null
closes the connection after receiving the expected data,
letting the tests proceed.

This is just a suggestion for n00b-friendliness. Running
interactively is rare, but it's exactly where a n00b
will begin, and the hang costs a little time and energy
to track down.
