parse.y: Fix the lineno of nd_set_line

* parse.y: Follow up of r61676. r61676 removed
  ruby_sourceline from some actions. When stop to
  use lineno of "n th" symbol, it's better to
  use last location's lineno of "n-1 th" symbol.

  e.g.

  ```
  primary : k_begin {} bodystmt k_end
  ```

  Before r61676 we use lineno of `@2` (ruby_sourceline).
  In this case, last location's lineno of `k_begin` (`@1`)
  is suitable.
