Subject: [PATCH] Refactored the code that adds Domain Users to BUILTIN\Users
 to use the new helper functions.

- Modified create_builtin_users to take in the domain sid to reduce the number
of times it needs to be looked up.
- Changed create_builtin_users to call the new helper functions.
- Changed create_local_nt_token to call the new version of create_builtin_users
and handle the new error that can be returned.
