Subject: [PATCH] nixos/incus: fix incus containers being wrongly restarted on
 package update whilst softDaemonRestart is set

When softDaemonRestart is enabled, containers and virtual machines still get restarted when incus updates
Disabling stopIfChanged on both incus-startup and incus fixes this
