impure.nix: fix handling of localSystem
If we passed a localSystem in, we don’t want the current system to
override it. Now we check for localSystem first to avoid getting
"mixed" localSystem values from commands like this:
nix-build --arg localSystem '{config="x86_64-unknown-linux-musl";}' -A hello
Which would eventually evaluate localSystem to this:
{
config = "x86_64-unknown-linux-musl";
system = "x86_64-darwin";
}
& Nix would not be able to run it correctly.
Fixes #41599
