Print only one error message if a build fails
E.g. instead of error: --- BuildError ----------------------------------------------- nix builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1 error: --- Error ---------------------------------------------------- nix build of '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed we now get error: --- Error ---------------------------------------------------- nix builder for '/nix/store/03nk0a3n8h2948k4lqfgnnmym7knkcma-foo.drv' failed with exit code 1
