Support non-apt OS, fix sysvinit autologin

Refine LXC container bootstrap and sysvinit autologin handling.

- Fix case branch formatting and change Debian-family check to an elif to avoid logic fall-through.
- Add a non-apt branch for Fedora/Rocky/Alma/CentOS/openEuler/openSUSE/Arch/Gentoo that sets the container timezone from the host and ensures curl is installed via the appropriate package manager.
- Improve sysvinit (/etc/inittab) auto-login changes: use more robust sed patterns, append a console autologin entry via heredoc, signal init to reload inittab before killing getty processes, and target getty processes more precisely to ensure proper respawn with new settings.
