Correct conditional logic in PIF check

The original conditional expression used incorrect syntax for grouping within [[ ]]. This commit corrects the logic to use || (OR) instead of && (AND) and removes the erroneous parentheses. This ensures the script accurately checks if the Play Integrity Fix module directory exists and contains a valid module.prop file.
