Revert "Constify SystemTime methods"

This reverts https://github.com/rust-lang/rust/pull/144519. The const-hacks introduces bugs, and they make the code harder to maintain. Let's wait until we can constify these functions without changing their implementation.

Fixes https://github.com/rust-lang/rust/issues/146228.
Closes https://github.com/rust-lang/rust/issues/144517 (since the feature is gone).

fix cfg for poison test macro

Fixes test regression in https://github.com/rust-lang/rust/pull/144648
Continuation of https://github.com/rust-lang/rust/pull/146433

I think this is right? Not really sure how to test this myself to be honest.

r? ```@RalfJung```

I'll also leave the improvement to the test macro for a separate PR (described [here](https://github.com/rust-lang/rust/pull/146433#issuecomment-3280210451)) since I've never done something like that before. Though since this fixes all of the tests, it might not be necessary since anyone in the future will see the `cfg()` and not `cfg_attr()`?
