Write to bench.out-tmp only once
Appending benchmark program output on every run could result in a case where the benchmark run was cancelled, resulting in a partially written file. This file gets used again on the next run, resulting in results being appended to old results. It could have been possible to remove the file before every benchmark run, but it is easier to just write the output to bench.out-tmp only once.
