Handle AnimatorSet durations > MAXINT

It is possible to create an AnimatorSet with child animators
that have durations (including repeatCounts) totalling more
than MAXINT. This causes a long->int cast to fail and
starting that set to fail due to bad sorting logic.

One-liner fix to avoid auto-casting in this case.
