Normally localed would do an approximate parsing of the Xorg config file
to determine the XKB keyboard layout.  This doesn't make sense on Guix
where there's no such file in /etc, and where the keyboard layout is
known statically at configuration time.

This patch removes the XOrg configuration parsing and expects to read the
configuration from environment variables instead.  It also removes the
stateful bits that would write configuration to /etc/vconsole.conf
and /etc/X11, which are unused in Guix anyway.

Patch by Ludovic Courtès <ludo@gnu.org>.
