[PATCH v4 8/8] babel: Update RFC references to new standards track RFC8966

[Toke Høiland-Jørgensen]

From: Toke Høiland-Jørgensen <toke at toke.dk>

The new standards track version of the Babel protocol was finally published
as an RFC. This has been the version of the protocol implemented by Bird
all along, but now that it has an RFC number we can update all the
references to the standard in the docs and code.
