added last login toggle

[Tearran]

Description

This pull request implements a function to reduce clutter by disabling the display of the last login message when connected via SSH. It addresses issue armbian/build/pull/7154 from the armbian/build repository. The change is motivated by the desire to make SSH sessions cleaner by hiding this message, which can be unnecessary and distracting for users.

Issue reference: #78
Related documentation: Armbian Documentation

Implementation Details

• Key changes introduced by this PR:

  • Added a command to sed that disables the display of the last login message by setting PrintLastLog to no in the SSH configuration file.
  • Added a toggle helper function and corresponding menu items to manage this setting.

• Justification for the changes:

  • The PrintLastLog option can clutter SSH sessions with unnecessary information. Disabling it will streamline the user experience and reduce visual clutter.

• Confirmation that no new external dependencies or modules have been introduced:

  • The changes only involve modifications to the SSH configuration and do not introduce new external dependencies.

Documentation Summary

• Metadata Included:

  • Yes, the necessary metadata for modules, jobs, and runtime has been included in the code.

• Document Generated:

  • The updated documentation was generated using armbian-configng --doc. The command was run to ensure README.md and other relevant documentation are up to date.

Testing Procedure

• Test 1:

  • Description: Verified that the PrintLastLog setting is correctly updated in the SSH configuration file.
  • Results: The configuration file correctly reflects the change to PrintLastLog no and restarts the SSH service successfully.

• Test 2:

  • Description: Tested toggling the setting via the new menu items.
  • Results: The setting was successfully toggled on and off, and the SSH service restarted appropriately to apply changes.
