examples: fix unset OPTIONS variable warning in systemd services

Modify chronyd.service to handle cases where OPTIONS is undefined,
which occurs when /etc/sysconfig/chronyd doesn't exist or doesn't set
the variable. This prevents the warning:

 "chronyd.service: Referenced but unset environment variable
  evaluates to an empty string: OPTIONS"
