scripts: improve checkstack

Cleanup checkstack script:
  * Turn on strict checking
  * Fix resulting error message because the declaration syntax
    was incorrect.
  * Remove incorrect and misleading use of prototype
     - prototype not required for this type of sort function
       because $a and $b are being used in this contex
     - if prototype was being used it should be for both arguments
  * Use closure for sort function
