[Buildroot] [PATCH v2 12/14] package/systemd: pre-create directory for timesync user

[Norbert Lange]

On an read-only filesystem the timesync service will not start
as the state directory cant be created.
If the directory exists, then the service can start,
obviously wont safe its state, but will otherwise work.
