9pfs: suppress performance warnings on qtest runs
Don't trigger any performance warning if we're just running test cases, because tests intentionally run for edge cases. So far performance warnings were suppressed for the 'synth' fs driver backend only. This patch suppresses them for all 9p fs driver backends.
