CRITICAL FIX: Override live-config sysvinit script causing autologin failure

Root Cause Identified:
- live-config script /usr/lib/live/config/0160-sysvinit was overwriting inittab at runtime
- Script was replacing all getty entries with '/bin/login -f user' instead of root
- This happened AFTER our inittab modifications during boot process

Solution:
- Created override-live-config-sysvinit.hook.chroot to replace the problematic script
- New script forces LIVE_USERNAME=root instead of default 'user'
- Uses proper traditional getty -a syntax: /sbin/getty -a root 38400 tty1
- Maintains tty2-6 as normal login shells for debugging

This should finally resolve the autologin issue by preventing live-config from
overwriting our carefully crafted inittab entries during boot.
