Update test to match new behavior of HdrHistogram

There was a [change in behavior in HdrHistogram][1] that causes the
tests to fail with the new version. The fix here is to add another value
in the test data set for the failing test, which has the result of
making both versions of HdrHistogram agree on the percentile values.
