pkg: Add LCOW init package

Browse Source 
This package build the init filesystem for LCOW (Linux Containers
on Windows) based on the instructions from:
https://github.com/Microsoft/opengcs.git

We also pull in a udhcpd config script from a specific version of
busybox which was the tip of master at the time this was added.
