Added a script to generate a linux appliance out of a ebbrt linux
binary.  In particular it creates a app directory with a linux kernel
and an initrd that contains the ebbrt binary along with all its library
dependencies.  It also generates in the initrd a custom init script
that boots the kernel and then launches the ebbrt binary when the
ebbrt binary exits the system power's down.
