This change allows to build automatically packages.nasqueron.org
FreeBSD part with portshaker and poudriere:

1. portshaker allows to merge the FreeBSD ports tree with our Nasqueron ports tree rPORTS into a consolidated ports tree we can use as a base to build
2. portshaker merged ports metadata can be used a a source to get the list of ports to build
3. poudriere can build this set of ports and their dependencies

Ref T1850 for FreeBSD packages.

Ref T2039 for poudriere scope.
