[#615] pilorama: Speedup TestForest_ApplyRandom()

Some of our pilorama tests fail on CI.
The reasons are not obvious, but one possible improvement
is using `WithNoSync` option for these. It should have much effect,
because we are writing on the tmpfs, but doesn't hurt anyway.

If I replace `t.TempDir()` with a local directory, test execution time
goes down from 5s (sync) to 0.4s (nosync), which is the same time as
with `t.TempDir()`. Maybe we have some strange CI configuration.

```
