Revert "The correct type for the askForPassword is boolean"

This reverts commit c2a7258f28438d147492ec39b873aa464515ce74.

I believe that `askForPassword` actually is an integer. To demonstrate:

```bash
$ /usr/bin/defaults read-type com.apple.screensaver askForPassword
Type is integer
```

As is, this commit is creating a perma-diff for me as the integer value isn't equal to a boolean.
