Title: nixos: Add support for changing supported systems

release.nix and release-combined.nix current hardcode the systems which
they are built for. This change introduces an argument to the
expressions called supportedSystems, which allows the builder to choose
which architectures he wants to build. By default, this uses the same
linux x86_64 and i686 architectures.
