PF ruleset. This is not a complete block on _pbuild being able to communicate (e.g. non-TCP/UDP protocols don't have a PCB with userid, so PF can't restrict in those cases) but avoids some cases, and in particular makes it more obvious when a port does things like download extra distfiles or dependencies as part of the build process. Slight tweak from a diff by espie@.
