parse.y: Fix a location of hash keys

* parse.y: Use @1 to only include a range of tLABEL.

  e.g. The locations of the NODE_LIT(:b) is fixed:

  ```
  a(1, b: 10)
  ```

  * Before

  ```
  NODE_LIT (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 10)
  ```

  * After

  ```
  NODE_LIT (line: 1, first_lineno: 1, first_column: 5, last_lineno: 1, last_column: 7)
  ```
