Update the last location of NODE_ARRAY

* parse.y (list_append_gen, list_concat): Update
  the last location of NODE_ARRAY when an item is
  appended or concatenated with another NODE_ARRAY.

  e.g. The locations of NODE_ARRAY is fixed:

  ```
  a(1,2,3)
  ```

  * Before

  ```
  NODE_ARRAY (line: 1, first_lineno: 1, first_column: 2, last_lineno: 1, last_column: 3)
  ```

  * After

  ```
  NODE_ARRAY (line: 1, first_lineno: 1, first_column: 2, last_lineno: 1, last_column: 7)
  ```
