Fix CircleCI build problems (#808)

* CircleCI: debian:10 docker based. Give possitility to override CACHE_VERSION through CircleCI when needed
* Makefile: fix #799 with implementation of @osresearch's recommended https://github.com/osresearch/heads/issues/799#issuecomment-673059028
* modules/coreboot : indentation fix and putting version hashes together to facilitate future maintainership.
