synclist: Only sync network configuration and uuid

There's a scenario where the root password can be disabled,
which would be synced as part of the synclist via the password/shadow
files, and if a chip switch occurs, the BMC would be locked out
because not all the app configuration files are synced to for example
enable LDAP.
To avoid issues, just sync the network configuration information so
that if the BMC is setup with a static IP that the user still has
easy access to it, the machine id (uuid) which is used by systemd
on startup, and hostname.
