[dunfell/master PATCH 4/6] recipes-core: images: Add a basic bootstrap base image

["Nishanth Menon" <nm@ti.com>]

Since we do not wish to modify the tiny-image from anything but really
tiny, lets use that infrastructure and add the bootstrap package group
to create initramfs (not exactly a completely usable system) which can
be used for basic board bringup.

This generates cpio around 36-40MB which should be usually fine for
even smaller systems (Ofcourse, this is much larger than tiny-image
which is around 6MB size). The packages are organized per size to
allow easier customization if desired.

This image follows the Bring Your Own Kernel model from
tisdk-tiny-image.
