czechlight-cfg-fs: replace NACM restore service with a migration
Currently we reinitialize ietf-netconf-acm module after each boot by
importing a set of rules. This means that after each boot the NACM
configuration was overwritten with "our" configuration.
This is not what we want. Admin of our box might want to adjust the
NACM rules as he see fit.
Therefore it makes sense to create a migration that sets the default
NACM rules by us and other people can modify them.
When migrating to this OS version (config version 4) we overwrite any
existing NACM rules for the last time as a part of the migration.
Starting from this version users are free to adjust the NACM rules
as they see fit. These rules *will not* be reset at boot time anymore.
We scanned the git and gerrit history for the reason why NACM rules
were not moved to one of the first migrations but we found nothing on
that. So this is probably just one of the skeletons in the cupboard that
is being removed with this commit.

- migrations to system configuration are applied via [`czechlight-migrate.service`](../package/czechlight-cfg-fs/czechlight-migrate.service),
- configuration of the Netopeer server gets re-checked via `netopeer2-setup.service` (once again in our Buildroot patches); this is needed especially during the first boot with no previous configuration to restore,
-- configuration of NACM is applied via [`nacm-restore.service`](../package/czechlight-cfg-fs/nacm-restore.service),
- finally, any daemons that use sysrepo are started.
We are also [using a `tmpfs` mount at `/run/sysrepo`](../package/reset-sysrepo/run-sysrepo.mount) that [gets wiped out whenever a sysrepo service fails](../package/reset-sysrepo/reset-sysrepo.mk).
