Vincent Ambo 31516eb9cd fix(buildTypedGo): Use builtins.baseNameOf when renaming inputs
Without this, we would end up with "double" store paths like this:

  /nix/store/848js1fvbjniv5n00hifmhgzzszl97vv--nix-store-ad6piq18wdkxnfzsbyn88ixvv7gfb1dp-main.go.drv

We really only care about the `main.go` bit though.
