run-pass/lang-item-public.rs is ignored on windows

I'm about to ignore this test with the removal of check-fast (it was implicitly ignored before). I'm not sure why this test is failing:

---- [run-pass] run-pass/lang-item-public.rs stdout ----

Triage: this test is still ignored

Here's a link to the test case: https://github.com/rust-lang/rust/blob/ca4b9674c26c1de07a2042cb68e6a062d7184cef/src/test/run-pass/lang-item-public.rs
