util/docker: Add docker files for coreboot-sdk & jenkins builders

Add the coreboot specific docker configuration files to the coreboot
repo.  These have been copied directly from Patrick's repo where they
had been being stored.

- coreboot-sdk: debian sid with the coreboot toolchain
- coreboot-jenkins-node: built on top of the coreboot-sdk, adds the
pieces required for building everything with the coreboot jenkins
builders.
