packaging: coco-guest-components: Allow building the project

The Confidential Containers guest-components will, in the very short
future, be part of the Kata Containers rootfs that's used by the
Confidential Containers usecase.

This commit introduces the ability to, standalone, build the component
locally and as part of our CI, and this can be done by calling:
`make coco-guest-components-tarball`
