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
