[OE-core] [PATCH 1/1] default-distrovars.inc, task-core-boot.bb: Create distro overridable varibales

[Khem Raj]

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
