Fix test flake in animation-state-changes-positive-playback-rate.html

The flake is caused by limited precision of timeline times. When
comparing times with >=, the boundary time needs to factor in error
tolerance.

The virtual/threaded-no-composited-antialiasing variant of this test
had a recent flake score of 954.
