[corlib] Bump allowed diff time in FileTest.LastWriteTimeSubMs

I've seen it fail with this:

```
1) LastWriteTimeSubMs (MonoTests.System.IO.FileTest.LastWriteTimeSubMs)
     Iteration #22 failed, diff.TotalSeconds: 1.000023, untouched: 20:14:03:0000000, now: 20:14:04:0000230
  Expected: True
  But was:  False
```
