The tests still fail after being split into multiple files, (2 out of 30 runs in roughly 48 hours) and the causes are missing target frames in the samples. This patch moves them to sequential to observe if the flakiness can be fixed when the tests are run on a system with less load. If the flake ever shows up again even after the tests are moved to sequential, we should consider make the test conditions more lenient - that is, we would only assert that there are *some* frames in the generated CPU profile but do not look for the target function there.
