docs(poudriere): point port section at canonical colibri port; fix MIT→AGPLv3

The inline Makefile example claimed LICENSE=MIT (wrong — colibri is
AGPL-3.0-only) and duplicated what now lives canonically in
colibri/packaging/freebsd/port/. Replace the snippet with a pointer + the
corrected key facts (license, binaries shipped, generated files).

 **Makefile** (Rust port pattern):

-PORTVERSION=    0.0.1
-CATEGORIES= sysutils
-MASTER_SITES=   https://code.smilepowered.org/clawdie/colibri/archive/
-DISTNAME=   ${PORTNAME}-${PORTVERSION}
+The port files are maintained in the **colibri** repo (source-of-truth, kept
+with the code) at `packaging/freebsd/port/sysutils/colibri/` — `Makefile`,
+`pkg-descr`, `pkg-plist`, plus a README covering generation. Don't hand-copy a
