Previously, the buildkite users were not able to traverse there. Removing /nix/var/nix/gcroots/buildkite/canon might not be needed, and is racy with other anchor step - the first one might still be building `ci.gcroot` (and didn't create the new symlink), so the second one will fail trying to remove the non-existing symlink.
