[PATCH 02/24] scripts: include scripts/include for all host tools

[Sascha Hauer <s.hauer@pengutronix.de>]

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

We already have one implementation of list.h, so we do not need to
replicate it of Kconfig specially. Make use of scripts/include for all
host tools to align us with what Linux is doing.
