Vincent Batts 37cabec013 graph: exported images times matching creation ...

the image export, that is used in `docker save` previous has just had
the layers times (atimes, mtimes) be when the save was done.
```bash
vbatts@valse ~ (master) $ docker save busybox | tar tv

With this change, the layer's directory and artifact will have times
matching the image layer's created time. The "repositories" file is set
to epoch.

Side effect of this is that the tar stream from `docker save` is now
more deterministic.
