[BUGFIX] Felogin allows redirect to any site

With #86219 the migration from sys_domain records to Sites was faulty.
Formerly all known domain records were inspected in order to decide
whether a domain was local or not.

This was changed to an invalid check covering the current site only.

This change now again validates all known sites.
