dns/knot3 update to 3.3.4

Hi,

a new version of this port has been released two month ago. 

The maintainer normally updates knot3 shortly after the release of a new version. He didn't react on a mail of mine. No pun intended, there are numerous reasons for that.

I do have a git-diff patch at hand, successfully compiling with poudriere, and running well for 1 month now.

What can I do to get this patch committed? 
Shall I create a PR like https://cgit.freebsd.org/ports/commit/?id=11f44f375254e07a262455aaf8311bfd4bbedb67

Regards,
Michael
