One more step on the path of the great refactoring. Touches rwfolder a little bit since it uses the Lstat from fs as well, but mostly this is just on the scanner as rwfolder is scheduled for a later refactor. There are a couple of usages of fs.DefaultFilesystem that will in the end become a filesystem injected from the top, but that comes later.
