maint(common): disable path conversions on Windows

By default Git Bash converts paths starting with `/`, so running the
docker image fails with errors or files mentioning `\Program Files\Git\`.
This change adds a wrapper function that prevents the conversion
and thus uses the paths in the correct form when calling docker.
