Patrick Ohly bf1188d292 scheduler_perf: only store log output after failures
Reconfiguring the logging infrastructure with a per-test output file mimicks
the behavior of per-test output (log output captured only on failures) while
still using the normal logging code, which is important for benchmarking.

To enable this behavior, the ARTIFACT env variable must be set.
