main: quit when the stream ends

I can't see this staying so simple for very long, but for now
this at least enables making rototiller-based rkt-sequenced demos
that exit gracefully when they're finished.

In a future where rtv may play embedded rkt configs+tracks, it
needs a way to detect the end of stream without making main exit.

But I'll cross that bridge when I get there...
