Test suite passes on the ROCm platform.

[joaander]

Description

Changes needed so the test suite passes on OLCF Frontier.

1. Fix the test_clusters.py seg fault.
2. Mark test_pivot_moves as xfail on ROCm platform: hpmc.update.Clusters produces incorrect results on the ROCm platform. #1605.
3. Skip test_force_energy_relationship[GPU-Tersoff] as xfail on ROCm platform: test_force_energy_relationship[GPU-Tersoff] fails on ROCm backend #1606.

The tmp_path change is necessary to allow pytest to run in user's home directories on Frontier.

Motivation and context

Builds on Frontier should pass pytest hoomd. The root causes of the problems in #1605 and #1606 are not apparent at this time. I am using pytest.xfail to mark the failing test and pytest.skip to skip the test that causes a seg fault.

Resolves #1479

How has this been tested?

I built HOOMD and ran pytest on OLCF Frontier.

Change log

Fixed:

* Access valid GPU memory in `hoomd.hpmc.update.Clusters`.
* Test suite passes on the ROCm GPU platform.
