Jon Ross-Perkins a7939ab22f Fix test_arg for file_test.subset (#2863) ...

I believe this broke when I was changing path handling.

Bad:

```
  bazel test //testing/file_test:file_test_base_test.subset --test_arg=/usr/local/...elided.../execroot/carbon/bazel-out/k8-fastbuild/bin/testing/file_test/file_test_base_test.runfiles/carbon/testing/file_test/example.carbon
```

Good:

```
  bazel test //testing/file_test:file_test_base_test.subset --test_arg=testing/file_test/example.carbon
```
