Fix upsampling test case on ppc (#32786)
Summary:
Power and x86 are giving slightly different results when scaling images up using `torch.nn.functional.interpolate` and when using OpenCV's `resize`. This is causing `test_upsampling_not_recompute_scale_factor` to fail on Power, but not x86. This changes the expected value to what OpenCV on Power produces if the test case is running on Power as well.
