…k-Simulacrum compiletest: don't use `std::io::stdout()`, as it bypasses `set_print`. This PR undoes a change made during rust-lang#69916, which became unnecessary during review but was left in by accident, and which isn't correct due to `libtest` using `std::io::set_print`, which overwrites the `println!` behavior but *not* `writeln!(std::io::stdout(), ...)`. The effect of using `writeln!(std::io::stdout(), ...)` was that the diff output would show *while* running the tests, instead of at the end, when failing tests are listed. r? @Mark-Simulacrum cc @oli-obk
