Update "BSD" license.

Portlint's history goes back to itojun. I've researched his open source
projects and he either used two licenses:

BSD3CLAUSE: magicpoint, sch
His own license: portlint, snooper, various camera tools, etc

Debian asked him years ago about his license to see if it complies with
thier DFSG:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=88416

Example of his license:

Hope I'm not crossing any boundaries here, but in my effort to clean up
"BSD" licenses in the ports tree this one certainly is not and sadly we
can't just ask him.
