Bug#939389: light-locker: Does not work in buster with xfce4

[Anton Ivanov <anton.ivanov@kot-begemot.co.uk>]

I tried to trace it sticking debug echoes into Xsession.d scripts

It is not set to start off with and even if it was 
95dbus_update-activation-env

will unset it. Lines 8-10 in that are:

    unset XDG_SEAT
    unset XDG_SESSION_ID
    unset XDG_VTNR
