test `to_string_in_format_args_incremental` fails in a read-only working directory

[Noratrieb]

Description

The test creates a file in the current working directory, which doesn't work in rust-lang/rust CI. It should be changed to create the incremental directory somewhere else, I'm not sure what the best solution would be here.

//@run-rustfix
//@compile-flags: -C incremental=target/debug/test/incr

// see https://github.com/rust-lang/rust-clippy/issues/10969

fn main() {
    let s = "Hello, world!";
    println!("{}", s.to_string());
}

I deleted the test in rust-lang/rust#113450 so it will be removed in the next sync.

We could add some variable-replacement scheme so that we can specify $TMP_DIR which would give every test its very own temporary directory
