This is a continuation of attempts to fix provlems with Windows CI hosts
getting into a broken state due to `.git` directory becoming a file for
random submodules for unknown reason.
Instead of relying on Jenkins functionality of `cleanWs()` function
provided by the [Workspace Cleanup Plugin](https://plugins.jenkins.io/ws-cleanup)
we use Git which should be more reliable, and possibly also speed up the
initial checkout of the repo and submodules.
A nice side-effect is that the repo checkout on all builds after the first
one takes ~1 minute instead of ~5 minutes.

By using `s3cmd` through PowerShell instead of Git Bash we improve
upload speeds on Windows slightly, as described here:
