bitbake: fetch2/wget: Set localfile for directories

If we wget something which looks directory like we end up with lock files
and done stamps without names, they also all use the same lockfile.

This change ensures that we use separate lock files based on the url
and avoid creating the mysterious ${DL_DIR}/.done files.
