Suppress writing xorg.conf.d snippets for built in evdev defaults

This should allow us to keep a cleaner xorg.conf.d snippet when
generated at boot without specific configuration which should then
allow udev rules to override it without any problem.

Note: we default to a pc105 layout but evdev defaults to a pc104
layout. We should either adopt pc104, or adapt evdev to default to
pc105.
