You'll either need some sort of daemon that sits around and waits to be told to shut down, or a setuid script owned by root. Be very careful with that, anyone who runs it gets a process running as root.

runit(8) System Manager's Manual runit(8)
NAME
runit - a UNIX process no 1
SYNOPSIS
runit
DESCRIPTION
runit must be run as Unix process no 1. It performs the system's booting, running, and shutdown in three stages:
STAGE 1
runit runs /etc/runit/1 and waits for it to terminate. The system's one time tasks are done here. /etc/runit/1 has full control of
/dev/console to be able to start an emergency shell if the one time initialization tasks fail. If /etc/runit/1 crashes, or exits 100, runit
will skip stage 2 and enter stage 3.
STAGE 2
runit runs /etc/runit/2, which should not return until system shutdown; if it crashes, or exits 111, it will be restarted. Normally
/etc/runit/2 starts runsvdir(8). runit is able to handle the ctrl-alt-del keyboard request in stage 2, see below.
STAGE 3
If runit is told to shutdown the system, or stage 2 returns, it terminates stage 2 if it is running, and runs /etc/runit/3. The systems
tasks to shutdown and possibly halt or reboot the system are done here. If stage 3 returns, runit checks if the file /etc/runit/reboot
exists and has the execute by owner permission set. If so, the system is rebooted, it's halted otherwise.
CTRL-ALT-DEL
If runit receives the ctrl-alt-del keyboard request and the file /etc/runit/ctrlaltdel exists and has the execute by owner permission set,
runit runs /etc/runit/ctrlaltdel, waits for it to terminate, and then sends itself a CONT signal.
SIGNALS
runit only accepts signals in stage 2.
If runit receives a CONT signal and the file /etc/runit/stopit exists and has the execute by owner permission set, runit is told to shut-
down the system.
if runit receives an INT signal, a ctrl-alt-del keyboard request is triggered.
