postfix: upgrade 3.6.4 -> 3.6.5

ChangeLog:
https://www.postfix.org/announcements/postfix-3.6.5.html

* Drop 0006-correct-signature-of-closefrom-API.patch as the issue has
been fixed upstream.

* Update main.cf to eliminate startup warning:
postfix: Postfix is running with backwards-compatible default settings
postfix: See http://www.postfix.org/COMPATIBILITY_README.html for details
postfix: To disable backwards compatibility use "postconf compatibility_level=3.6" and "postfix reload"
