Here's what I have in the plist:

@(root,operator,04554,) /sbin/shutdown

I'll note that ping/ping6 also have similar, and they install setuid

@(root,wheel,04555,) /sbin/ping
@(root,wheel,04555,) /sbin/ping6

Here's what I have in the pkg tarball:

# tar tvf FreeBSD-runtime-12.0.s20171204170123.txz | grep shutdown
hr-sr-xr--  0 root   operator     0 Dec  4 17:05 /sbin/shutdown link to

# tar tvf FreeBSD-runtime-12.0.s20171204170123.txz | grep poweroff
-r-xr-xr--  0 root   wheel    15440 Dec  4 17:05 /sbin/poweroff
hr-sr-xr--  0 root   operator     0 Dec  4 17:05 /sbin/shutdown link to

And installing it again sure enough gives version without setuid:

# pkg-static add -f FreeBSD-runtime-12.0.s20171204170123.txz
