Ensure user sys is secured

MediaNivel 1Automatizadaaix

Descripción

This change locks and disables login access for the sys user account. This change disables direct local and remote login to the sys user account. Do not set a password on this account to ensure that the only access is via su from the root account. There should not be a requirement to log in as the sys user directly. Audit: `lsuser -a account_locked login rlogin sys` must show true/false/false; an absent account is compliant.
