Philip Withnall 6b8240f061 tests: Fix performance-threaded test when run for zero seconds
When running the test with `-s 0` it would previously crash. Fix that,
and make it so that it only does a single test run in that case.

This will be useful in an upcoming commit for smoketesting the test to
avoid bitrot.
