[meta-arago][scarthgap][PATCH 1/2] emptty: backport fix for signal handeling

[<rs@ti.com>]

From: Randolph Sapp <rs@ti.com>

To quote the upstream patch:

	Emptty cannot currently exit via an external signal if the
	session process exits abnormally. This conflicts with the
	expected behavior of systemd, which expects that the service
	will always respect signals.

	This has the added benefit of allowing users to use ^C to
	restart the login process at any point in the menu system.

Backporting this since it hasn't hit a tagged release yet.
