Update net/chrony: enable privilege separation and other minor changes.

- enables privilege separation
- removes the build dependency on asciidoctor
- removes the runtime dependency on makeinfo and readline
- add a runtime dependency on libedit
- do not install the HTML documentation (in favour of man pages)
- update the post-install message (pkg-message) in light of privilege separation
- set the permission of /var/db/chrony to the new "chronyd" user and group
