[patch] xdm doesn't clear wtmp/utmp entry after log out

[patrick keshishian]

Hi,

I've noticed this issue for sometime now. I was hoping one
of the Xorg updates would fix it, so finally I decided to
read some man pages, specifically sessreg.

Evidently the Xservers path is not correct (or has changed)
in OBSD's install. No longer found at:

        /usr/X11R6/lib/X11/xdm/Xservers
is at:
        /etc/X11/xdm/Xservers

[pre-patch]
Log into X using xdm, then log out. Alt+Ctrl+F1 login and
run last as such:
$ last -5
sidster   :                                 Tue Jan 13 12:01   still logged in
sidster   ttyC0                             Sat Jan 10 16:35   still logged in
reboot    ~                                 Sat Jan 10 16:35
shutdown  ~                                 Sat Jan 10 16:34
root      ttyC0                             Sat Jan 10 16:28 - shutdown  (00:06)

[post-patch below (loally modified files)]
Same procedure as above:
$ last -5
sidster   :                                 Tue Jan 13 13:23 - 13:24  (00:00)
sidster   :                                 Tue Jan 13 12:01 - 13:23  (01:22)
sidster   ttyC0                             Sat Jan 10 16:35   still logged in
reboot    ~                                 Sat Jan 10 16:35
shutdown  ~                                 Sat Jan 10 16:34
