Previously, the Spark-rapids plugin only needs to call lists::drop_list_duplicates to create map which requires the input to be non-nullable. As such, the output of the JNI is just a lists column without bitmask. When operating on nullable input lists column, it produces incorrect results.

This PR fixes that.

Change looks good to me, but it would be nice to update the tests to verify the functionality and ensure the fix does not regress.
