remote: Chunker should open files lazily.

The Chunker should only open a file on the first call to next(). We
noticed that when remote executing with hundreds of actions in parallel
bazel would sometimes run out of file descriptors. That's because on
creating a new Chunker object it would already open a file, eventhough
the first call to next would happen at a much later stage.
