[arch-general] Set ip lan address /etc/environment

Hi Maykel,

To debug this kind of thing, e.g. to see if it even runs, intersperse
tee(1)s to files that can be inspected afterwards.

    ip="$(ifconfig | tee /tmp/d.ifc | grep -A 1 'eth0' | tail -1 | tee ...

> /etc/security/pam_env.conf :
> ip              DEFAULT=""      OVERRIDE="$(ifconfig | grep -A 1

I see nothing to suggest PAM supports sh's `$()' syntax, and wouldn't
expect it to.
