examples: drop chrony.spec

The example spec file was too limited to be recommended for use in any
rpm-based distribution, e.g. it didn't configure chronyd to drop the
root privileges.

Users that want to build a package from the latest source code should
start with the official package of their distribution.

-%description
-chrony is a client and server for the Network Time Protocol (NTP).
-This program keeps your computer's clock accurate. It was specially
-designed to support systems with intermittent Internet connections,
-but it also works well in permanently connected environments. It can
-also use hardware reference clocks, the system real-time clock, or
-manual input as time references.
