chronyd crash loop if Debian server is rebooted

This patch fixes the constant chrony container crash loop after (Debian 10) server is rebooted,
as described in Bug-ID: #1915528.

Due to permissions issue, before this fix is applied chronyd process will be exiting with
root cause error message:

Fatal error : Could not open configuration file /etc/chrony/chrony.conf : Permission denied
This has to do with priviledges we configured for chrony. Relaxing them fixes the issue.
Tested on top of stable/victoria and Debian 10 Buster.

Not tested on CentOS/RHEL. If this does not work well on RHEL/CentOS we can maybe parametrise
the owner and make it configurable (just one idea).

Closes-Bug: #1915528
