See https://github.com/macports/macports-ports/pull/17934. Borg upstream
seems to think the devil lurks behind every new minor release of the
msgpack library upstream and wants to whitelist them manually. Upstream
did that yesterday in

  https://github.com/borgbackup/borg/commit/2842463f21499e3cb0258283ba4f0e349e46678e,

and the PR above backports this change, since upstream has not yet
released a new version of borg with this change merged.
