scripts/build_spec.sh: new script
It allows to build single spec file inidividually using Photon OS
docker image. It does not depend on package builder.
It is known as SDK.
examples/build_spec/simple-module contain example spec file
demonstrating how to build kernel module (sources are in
module_example.tar.xz) for Photon OS.
It is known as NDK.
