This is a re-work of the patches previously submitted based on feedback from Dominick. Changes in userdomain to create an attribute (user_runtime_content_type) for files in /run/user/%(UID)/. Then changes in systemd_logind to use interfaces to delete various types with this attribute.
I think this is basically what Dominick was suggesting, but please comment if I have gotten something wrong or misinterpreted the suggestion.
While I have tested the changes I made I don't know what side effects this may have had on other domains that create directories and files in /run/user/%(UID)/*.
