[meta-arago,master/kirkstone] recipes-core: systemd: Fix Date and Time Service

- Currently oe-core's systemd-timesyncd defaults to Google's time servers. However those servers are not always reachable.
Even if they are, it is much more sensible to use pool servers from ntp.org and ubuntu. Hence, add a new timesyncd.conf file
for the same.

- For the above issue, oe-core maintainers suggested to use bbappends in own layers to point to the time servers suitable
for your projects [1]. Hence, use systemd_%.bbappend to install the newly created timesyncd.conf file in filesystem.

Agreed. Google ntp servers are not always reachable.
