Remove psutil patches from test_util.py "through-the-framework" tests

[ChrisKeefe]

Improvement Description
Remove psutil patches from test_cpu_request_through_framework() and test_more_threads_than_max_stripes()

Current Behavior
These tests are currently running on patched psutil results, due to a bug in psutil's handling of GHA's test runner hardware. This is fine for now, but a little gross.

Proposed Behavior
Remove patches, and let psutil run properly. Note: test runners have two cores, so tests should not call more than two cores.

Note: this PR may take care of our issue. Time to check whether psutil behaves as expected on our test runners. If yes, then we should be good to remove the patches from these tests.
