Remove now unused lang_items feature in IO primitives (#4596)

Browse Source 
We don't use any explicit `#[lang = ...]` items anymore (`panic_fmt`
is replaced with now-stable `#[panic_implementation]`, OOM is handled
via `alloc_error_handler` directly etc.), so I thought it'd be good to
remove it for clarity to limit used nightly features.
