This did not merge history, but that git-fu magic elludes me.
I accomplished this with the following code:

```shell
git remote add ocicert https://github.com/kinvolk/ocicert
git read-tree --prefix=test/ -u ocicert/master
```

Change copyright holder from "ocicert authors" to "The Linux

runtime-spec. Dongsu's authorship is preserved and the agreed work of
this effort by LF is recognized in this updated copyright holding.
