Create image class image-overlay and move phosphor to use it

This commit creates a new class image-overlay based on how the
image-live class is structured.  It takes parameters for the base
and overlayed file system types but the initfs only support ext4
over squashfs presently.

It then moves invoking the generation of the flash image from a
post image creation command to a separate task invoked from the
overlay image so that building the initramfs image by itself does
not try to create a flash image.

Building

OpenBMC uses Yocto/Open-Embedded for a build system, which supports an out-of-tree build. It is recommended that you create an empty directory somewhere to hold the build. This directory will get big.

On Ubuntu 14.04 the following packages are required to build the default target

sudo apt-get install -y git build-essential libsdl1.2-dev texinfo gawk chrpath diffstat

On Fedora 23 the following packages are required to build the default target:

sudo dnf install -y git patch diffstat texinfo chrpath SDL-devel bitbake
sudo dnf groupinstall "C Development Tools and Libraries"

To start a build:

cd <builddir>
. <repodir>/openbmc-env
bitbake obmc-phosphor-image
