Tests: Don't cd to the tests directory!

We:

1. Set up a nice TMPDIR for our tests to use
2. Immediately `cd` to the directory containing the test runner.

So instead we don't do (2), and stay in the temp directory, and
explicitly use all the things from the test runner directory.

I am fairly certain that cmake papered over this by adding a second
layer of temp dir.
