[SPARK-24950][SQL] DateTimeUtilsSuite daysToMillis and millisToDays fails 
w/java 8 181-b13

## What changes were proposed in this pull request?

- Update DateTimeUtilsSuite so that when testing roundtripping in daysToMillis 
and millisToDays multiple skipdates can be specified.
- Updated test so that both new years eve 2014 and new years day 2015 are 
skipped for kiribati time zones.  This is necessary as java versions pre 
181-b13 considered new years day 2015 to be skipped while susequent versions 
corrected this to new years eve.

## How was this patch tested?
Unit tests
