perf tests shell task_analyzer: Run this test exclusively

When running in the now default parallel mode this test has been
frequently failing, while when running exclusively, on a quiet system,
it passes.

Since its expectations were established when serial testing was the
norm, mark it as exclusive to get this kind of resunt:
