scripts/update-systemd-from-27-to-238.sh: Leave Unbound enabled

Due to several problems with systemd-resolved [1][2], we keep Unbound
for now as the local validating, recursive, and caching resolver.

Leave systemd-resolved running to have the D-Bus API. It will use the
resolvers from `/etc/resolv.conf`.
