recipetool: create: fix change in path structure if --extract-to path exists
If the directory specified by --extract-to exists, because we were using
shutil.move() to move the temporary extracted directory to the specified
path, a subdirectory was being created under that directory instead of
moving the contents, which was a different result than if the directory
didn't previously exist. We could try to always move the contents but
that's complicated when any symlinks are involved; the simplest thing is
just to remove the directory (which should be empty anyway) before
moving the temporary directory across in its place.
