[SPARK-5367][SQL] Support star expression in udfs

A follow up for apache#4163: support  `select array(key, *) from src`

Since  array(key, *)  will not go into this case
```
case Alias(f  UnresolvedFunction(_, args), name) if containsStar(args) =>
              val expandedArgs = args.flatMap {
                case s: Star => s.expand(child.output, resolver)
                case o => o :: Nil
              }
```
here added a case to cover the corner case of array.
