chrony: add support for config and source snippet includes

This makes it simpler to set specific config options or custom sources
by adding snippet files to /etc/chrony/conf.d/ or /etc/chrony/sources.d/
instead of modifying a copy of the full configuration file. As new
snippets can be added from separate recipes, targeted changes can be
done in multiple layers.

These specific directories are also used in Debian's default
configuration. It is not an error if they are missing.
