[SPARK-17182][SQL] Mark Collect as non-deterministic
## What changes were proposed in this pull request?
This PR marks the abstract class `Collect` as non-deterministic since the results of `CollectList` and `CollectSet` depend on the actual order of input rows.
## How was this patch tested?
Existing test cases should be enough.
