Mirrors bootstrap-host.sh in reverse: removes the sudoers rule and the
fix-lxc-apparmor.sh script it installed, so the elevated grant only stands
for the duration of an active deployment instead of indefinitely.
create-graylog-lxc.sh already degrades cleanly to its manual fallback when
the automation isn't present, so this is a safe no-op-adjacent revoke.
