This is a workaround for the fact that we currently need to run multiple
greeter sessions in multi-seat environments that use the same user. We
should not be doing this in the first place. Doing this effectively
prevents GNOME from using a systemd startup, which would cause relevant
processes to be outside of the session scope preventing lookups of the
logind session from the PID.

Instead, we really should be running each of the greeter session as a
separate (dynamic) user. But lacking that, this workaround should get
multi-seat support up and running again for the time being.
