[PATCH xinit] Remove workaround for xterm -L (#89653)

[Peter Hutterer]

The -L flag was removed in 1989.

This enables the legacy keyboard driver again when the server is started
with -keeptty (bd6cacdd3661)

No idea what exactly is going on here, I tried to bisect the server to get
some hints what triggers what there are too many moving targets. Either
way, with this patch applied, a basic xorg.conf that uses the kbd driver
works again with startx/xinit (provided a suid Xorg binary of course)

Thanks to alanc for digging up the commit that removed the -L option.
