nixos/grub: Insert required image modules for themes

Browse source 
With a limited testing of all packaged GRUB 2 themes (pkgs.nixos-grub2-theme)
this is tested to work.

Without this change, the theme loading will error out (waiting for a key press).

With this change, the theme loads and works as expected.
