Subject: [PATCH] activation: stub out for plan9

plan9 doesn't have syscall.CloseOnExec, causing anything using
`activation` to fail when building on plan9:

```
2024/05/03 12:12:51 Failed to run [go build --ldflags -s -X github.com/rclone/rclone/fs.Version=v1.67.0-beta.7911.f8ce568ca.merge -trimpath -o rclone-v1.67.0-beta.7911.f8ce568ca.merge-plan9-386/rclone -tags  ..]: exit status 1
2024/05/03 12:12:51 Command output was:
