This fixes two issues.
The first issue is that updater is maked for replan in Turris OS 3.x lists and it is replanned first becuase tos3to4-early depends on it. The solution here is to replan one more time after tos3to4-early installation that should be right after updater-ng is installed.
The second issue is that we migrate configuration from switch-config to DSA but kernel we are running in that moment does not support DSA and thus we end up with unconfigured LAN. This makes it hard to access router after migration and makes router pretty much broken. The reboot solves this as a new kernel is deployed. We do it this way without need for user to reboot device manually.
