[BOOTDATA] Disable logoff/password-change/workstation-lock in the LiveCD (reactos#8373)

- Disable "Log Off" from the Start Menu and the C-A-D Security dialog;

- Disable the "Lock Workstation" and "Change Password" buttons in the
  Security dialog.

These are only "UI"-usability features to prevent the user from
logging off when running the LiveCD. (Logging off from the SYSTEM
account, and changing its password, don't make much sense.)
