This makes `nc -l` do what it says it does, and listen for exactly one
connection before exiting, instead of handling connections until a ^C.

    terminal1$ echo foo | toybox nc -l -p 1234 > bar
    terminal1$ cat bar
    bar

    terminal2$ echo bar | toybox nc localhost 1234 > foo
    terminal2$ cat foo
    foo

(Unrelated: is matching the BSD netcat's command line interface a goal? I
keep
accidentally doing `toybox nc -l 1234` and getting bitten by it.)
