Cleanup Sudoers

[ashthespy]

We have quite some legacy: https://github.com/volumio/volumio3-os/blob/56d8f4e08ca3cb143324aa0740c362c469043a9b/scripts/volumio/volumioconfig.sh#L172-L174

• [ ] legacy commands: update-rc.d,
• [ ] outdated /bin/sh **/volumio_command_line_client/*.sh

Since changes to Buster are "Frozen" I suggest to add the clean-up to the Bookworm roadmap. Things like sysinit* will not have place - obsolete. Sorry - did not notice Bookworm label.
