[PATCH container] lxc: remove unused find_lxc_console_pids helper

[Filip Schauer <f.schauer@proxmox.com>]

The helper is no longer needed, as its only user was the stale LXC
console reaper in pve-manager, which was removed in
888c136dd303 ("fix #8093: pvestatd: remove stale lxc console reaper").

Drop the now dead code.
