This patch improves the clarity and grammar of output messages in the acct()
selftest. Minor changes were made to user-facing strings and comments to make
them easier to understand and more consistent with the kselftest style.

Changes include:
- Fixing grammar in printed messages and comments.
- Rewording error and success outputs for clarity and professionalism.
- Making the "root check" message more direct.

These updates improve readability without affecting test logic or behavior.
