std tests: use __OsLocalKeyInner from realstd

This is basically the same as https://github.com/rust-lang/rust/pull/100201, but for __OsLocalKeyInner:

Some std tests are failing in Miri on Windows because [this static](a377893da2/library/std/src/sys/windows/thread_local_key.rs (L234-L239)) is getting duplicated, and Miri does not handle that properly -- Miri does not support this magic `.CRT$XLB` linker section, but instead just looks up this particular hard-coded static in the standard library. This PR lets the test suite use the std static instead of having its own copy.

Fixes https://github.com/rust-lang/miri/issues/2754
