lib/systems: add emulatorAvailable
``` nix-repl> pkgsCross.arm-embedded.stdenv.hostPlatform.emulatorAvailable pkgsCross.arm-embedded.buildPackages false nix-repl> pkgsCross.aarch64-multiplatform.stdenv.hostPlatform.emulatorAvailable pkgsCross.aarch64-multiplatform.buildPackages true ``` will be useful for stuff like handling https://github.com/NixOS/nixpkgs/issues/187109
