desktop_vt: hackaround 'tty?' problem on F31

Browse Source 
On F31 update tests, desktop_vt is broken because the 'ps -C'
command is showing 'tty?' as the tty on which Xwayland/Xorg is
running. Let's try using loginctl as a workaround for this.
This ordering of commands should ensure the ps -C output takes
precedence when it's correct.
