path-lookup: move xdg_user_dirs() to xdg-autostart-generator

This is the only place where xdg_user_dir() is needed and
makes sense. All other invocations have been replaced with
user_search_dirs() - see previous commits for details.

+        * The --purge switch of systemd-tmpfiles (which was added in v256) has
+          been reworked: it will now only apply to tmpfiles.d/ lines marked
