net/openntpd: update to 6.8p1

6.8p1 - New release based on OpenBSD 6.8

	* The ntpd daemon now gets and sets the clock in a secure way when booting
	  even when a battery-backed clock is absent.

	* Improvements in DNS resolving and constraints checking, especially during
	  startup. Unreliable NTP peers are removed from the pool and DNS resolving
	  is repeated to add replacements.

	* Improved reliability and security of TLS constraint checking.

	* Improved logging of failure cases.

	* Prevent the case of multiple ntpds running at once by checking presence
	  of the local control socket.

	* TLS certificates are now searched in TLS_CA_CERT_FILE.

	* The default ntpd.conf configuration file now uses 9.9.9.9 and
	  2620:fe::fe, in addition to google.com, when performing time constraint
	  validation.

	* Improved handling unsynched mode when there is no replies from an NTP
	  server, such as when there are network connectivity issues.

	* To build OpenNTPD with time constraint support, libtls from LibreSSL
	  3.2.2 or later are recommended. LibreSSL 3.2.2 and later include a
	  self-contained libtls, which allows OpenNTPD to work with constraints
	  even on systems even where libcrypto and libssl are not from LibreSSL.

6.2p3 - Bug fixes

	* Fixed build on OS X

6.2p2 - Bug fixes

	* Fixed support for 'query from' and clarified usage.

6.2p1 - New release based on OpenBSD 6.2

	* Added option "query from <ip>" to ntpd.conf, to specify a local IP
	  address for outgoing NTP queries.

6.1p1 - New release based on OpenBSD 6.1

	* Quieted warnings about constraint connection retries.

	* Implemented fork+exec for ntpd child processes.

	* Added imsg inter-process reliability fixes.

	* Fixed memory leaks and reduced heap memory usage.

	* Numerous logging improvements and additions.

	* Added macOS 10.12 getentropy support.

	* Fixed arc4random blacklist use native implementations where
	  possible.
