tee: /usr/local/bin/k0s: Text file busy

Upgrading a cluster from one node to three nodes failed with the following log line:

> level=fatal msg="upload failed: Process exited with status 1 (tee: /usr/local/bin/k0s: Text file busy\n)"

Target OS: Alpine 3.15
k0sctl version: 0.13.0-rc.1-1-gaf2f60b (af2f60b896c1b4ba4f1e6016fe445d9cfa7fe247)
[k0sctl.log](https://github.com/k0sproject/k0sctl/files/8349044/k0sctl.log)

A second run of k0sctl also fails because it tries to join new controllers by requesting a token from the wrong node (the newly created one which hasn't been joined):

> time="25 Mar 22 10:29 CET" level=debug msg="[ssh] 10.83.134.16:22: executing `sudo -s /usr/local/bin/k0s token create --role controller --expiry 10m0s`"

Start with the attached k0sctl logs and the provided three-host YAML configuration; trace the upload during an upgrade on Alpine 3.15 and the controller-token request on the second run. Done means the upgrade succeeds without the “Text file busy” failure and new controllers request their token from the correct existing node.
