Port some integration tests to new test setup

The method I'm currently using (if other want to help) is:

* Add fmt.Println(b.DumpTxtar()) after the Build step
* Add that to a files var and pass that to Test(t, files) or similar
* Then, if possible, try to reduce the files/content down to what's needed in test.

Note that if the test is small, it's probably faster just to manually re-create the test.
