`nixos/modules/installer/kexec/kexec-boot.nix` doesn't contain any custom NixOS config, other than importing `netboot-minimal.nix` (which imports `netboot-base.nix`, which imports `netboot.nix`. `netboot.nix` really is just describing a self-contained system config, running entirely off kernel and initrd, so we might as well move the kexec script generation there as well. `netboot.nix` already contains some `system.build` attributes. Provide a `system.build.kexecTree` attribute (and `kexecScript` for composability).
