replace chrony with timesyncd

[andiradulescu]

Resolves #318

• removes chrony and replaces it with systemd-timesyncd
• makes time syncing faster than chrony and when network configuration or connectivity changes
• installed build and tested both with internet and without internet on boot - time is synced almost instantly after network connectivity is up

Once we get to #315, I can see all sorts of checks being add if the script is written generically enough. Then, we can easily test the reliability of these things in a loop.
