Fix UnitTestBoundingIntervalHierarchy test against nvcc
Nvcc cannot build UnitTestBoundingIntervalHierarchy.cu
by never terminating on Linux. On windows, it just refuses to compile. It's unclear whether it's a bug against CUDA 9.2 or a VTK-m one. For now we just disable it to keep the windows nightly build work. We should revisit this test when we have time.
