Subject: [PATCH] sd-login: read list of uids of sessions from UIDS not

 ACTIVE_SESSIONS

As described by Luke Shumaker:

  sd_seat_get_sessions looks at /run/systemd/seats/${seat_name}:SESSIONS to get

  the list of sessions (which I believe is correct), and at

  /run/systemd/seats/${seat_name}:ACTIVE_SESSIONS for the list of users (which

  I believe is incorrect); I believe that it should look at the UIDS field for

  the list of users. As far as I can tell, the ACTIVE_SESSIONS field is never

  even present in the seats file. I also believe that this has been broken

  since the function was first committed almost 6 years ago.

Fixes #5743.

(cherry picked from commit d3cfab3148de482649e22d9dbbfec6e967a80856)
