parse.y: Fix the last location of NODE_OPT_ARG

* parse.y (opt_arg_append): Update the last location of
  NODE_OPT_ARG when NODE is appended to the last.

  e.g. The locations of the first NODE_OPT_ARG is fixed:

  ```
  def a(b = 1, c = 2); end
  ```

  * Before

  ```
  NODE_OPT_ARG (line: 1, first_lineno: 1, first_column: 6, last_lineno: 1, last_column: 11)
  ```

  * After

  ```
  NODE_OPT_ARG (line: 1, first_lineno: 1, first_column: 6, last_lineno: 1, last_column: 18)
  ```
