Bug#1111200: deja-dup: 49 alpha is broken without newer rclone

[Michael Terry]

There's another route Debian could take, since updating rlcone might be a chore. Which is to backport the patches to fix OneDrive support:
- https://github.com/rclone/rclone/commit/aee8d909b3925df17f5e0c82348a2597bc3457ac
- https://github.com/rclone/rclone/commit/dedad9f071d81a2b6bf980d5f48d7997cae160af

Ubuntu applied those patches downstream (https://bugs.launchpad.net/ubuntu/+source/rclone/+bug/2076021). Maybe it would be easy to steal that debdiff.

This isn't just a Deja Dup thing, this is an "anyone using Rclone to talk to OneDrive" thing, so patching rclone would be nice, absent a more complete version upgrade.
