containerd: uprev to v1.0.2

Uprev containerd to v1.0.2 for compatibility with recent docker (18.04+)
builds.

With this uprev we also significantly restructure the build to use more
of the latest oe-core go build infrastructure, but non-standard parts of
the build remain.

We also allow containerd to be build with CGO enabled to avoid linkage
errors with the oe provided go build infrastructure.
