Rollup merge of #108507 - hermitcore:new, r=m-ou-se

Browse Source 
use `as_ptr` to determine the address of atomics

The PR #107736 renamed  atomic `as_mut_ptr` to `as_ptr`. Consequently, the futex implementation of the tier-3 platform `RutyHermit` has to use this new interface. In addition, this PR removes also an unused import.
