Set TERM=linux for console-getty.service

Browse Source 
Create a systemd override for console-getty.service inside LXC containers to set Environment=TERM=linux (written to /etc/systemd/system/console-getty.service.d/pve-console-term.conf) instead of touching getty@tty1/serial-getty unit dirs. This targets the noVNC/LXC console behavior where console-getty.service, not getty@tty1, is used and prevents agetty cursor-position queries from corrupting the noVNC login prompt. Also remove the older workaround in create_lxc_container that forced 'cmode: console' in the LXC config, since the new override addresses the issue.
