[OE-core] [PATCH 03/12] conf: Create distro overridable IMAGE varibales

[Saul Wold]

From: Khem Raj <raj.khem at gmail.com>

With default-setup being pulled in via bitbake.conf and task-core-boot
being pulled into all images in distros, we need
to have some variables that distro's can override if need be
This is a backport from angstrom/OE. It will help distros which
e.g. would like to use busybox-mdev instead of udev and similarly
for login manager these variables can be defined in distro policies
