make-stable: Implement a working dry run with nicer output

We can not use --link-dest when doing the dryrun as it will consider
everything up to date. So create some base args and then add the right
parts to it. Skip --checksum from the cli as it makes things really
slow. Use rsync (instead of diff -r) as this will be used for the final
handling. Keep on using sub dirs as this gives higher control. We could
otherwise just syncrhonize everything.
