cl/5832 added a global system parameter to depot which allowed specifying what `system` should be used for nixpkgs and all depot derivations (assuming a native compilation case) which was implemented in cl/5846. This allows instantiating derivations for a different system than whatever builtins.currentSystem happens to be. This is useful for debugging, allows you to schedule builds on build servers for other platforms or build for architectures that are a subset of the one you are running (e.g. i686-linux). This change eliminates all remaining uses of builtins.currentSystem which could lead to an inconsistent combination of `system` values when passing `localSystem`.
