This patch was meant to remove the trolling of /proc for uids but I
haven't got there yet.
I meant to use utmp as a fallback but I realized utmp does not deal with
uid numbers rather usernames, and I need to think if it makes sense to
go that way as it may be hairy when we use subdomains as now I need to
know what kind of user name was used (fully qualified or not etcc.).
So for now I left the old code as a fallback in case systemd is not
available or fails unexpectedly.
Ticket: #2084
