Unrolled build for rust-lang#121498

Rollup merge of rust-lang#121498 - flba-eb:make_timespec_capping_public, r=Nilstrieb

Make QNX/NTO specific "timespec capping" public to crate::sys

It is used in:

- `library/std/src/sys/locks/condvar/pthread.rs`
- `library/std/src/sys/pal/unix/thread_parking/pthread.rs`

This is probably required due to introduction of `sys/pal` and rust-lang#121177
