[meta-arago][scarthgap][PATCH 1/2] emptty: add version 0.13.0

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

Add emptty, a "Dead simple CLI Display Manager on TTY". This is a
relatively lightweight display manager that supports x11 as well as
wayland though both a CLI and automatic login mechanism.

This can effetely replace the custom init scripts for both x11
(xserver-nodm-init) and wayland (weston-init) with a single tool with
more verbose logging capabilities.

This also addresses the current issue of with weston occasionally
starting before all the required devices are registered with the drm
subsystem.
