TST/PKG: Move test HDF5 file to legacy
State: closed

@jreback this failed `pd.test()` from a not-git build, since our setup.py only include HDF5 files under the `legacy_hdf` directory.

```python
>>> pd.test(['-k', 'test_read_py2_hdf_file_in_py3'])
```

Comments:
Appveyor is a ways behind, so lmk if you're OK with merging before that finishes. Then I can cherry-pick and retag 0.20.3 (I haven't pushed yet, so it should be OK).
OK, Appveyor finished. Travis failed to start https://travis-ci.org/pandas-dev/pandas/jobs/251208991, but I'm merging anyway since it'll be tested on the backport branch.
yeah this is fine
