[OE-core] [PATCH] systemd-conf: add timesyncd.conf

[Cengiz Can]

Currently OE-Core's systemd-timesyncd defaults to Google's time servers.

However those servers are not always reachable.

```
systemd-timesyncd[242]:
  Timed out waiting for reply from 216.239.35.12:123 (time4.google.com).
systemd-timesyncd[242]:
  Timed out waiting for reply from 216.239.35.0:123 (time1.google.com).
systemd-timesyncd[242]:
  Timed out waiting for reply from 216.239.35.4:123 (time2.google.com).
systemd-timesyncd[242]:
  Timed out waiting for reply from 216.239.35.8:123 (time3.google.com).
systemd-timesyncd[242]:
  Timed out waiting for reply from 216.239.35.12:123 (time4.google.com).
```

Even if they are, it is much more sensible to use pool servers from
ntp.org.

This patch adds a default timesyncd.conf with Google's time servers
moved to Fallback and pool.ntp.org as primary time servers.
