This ovmf package is part of the community repository. We don't
want to "pollute" the Alpine base with it. Luckily it's juts a single
file which we can install and then copy to the base image.
The package is needed for qemu EFI boot.

The Dockerfile is now an input to the contents of the base image and
needs to be included in the hash calculation.
Also, make the Makefile, Dockerfile and pacakges file a dependency.

We use the "official" Alpine based Docker image and extract
the binary and libraries from it and add to the base. Compiling
it from source would require a Haskell setup...

This means that we limit to one place where we use network access
in building, and in future all other package builds can be deterministic.
