[FIX] auth_signup: invalid value on field signup_valid for non superuser

- The field `signup_valid` was computed and stored using the `superuser`
  env, which causes issue since it means the value was computed for the
  wrong environment.

  Using a compute_sudo instead of manually calling `sudo()` fixes the
  issue.

  e.g: reading signup_valid using a regular user (non superuser) will
       always return False, while doing it as the superuser will return
       the correct value.
