Rollup merge of #122730 - ferrocene:hoverbear/qnx-ucred-cfgs, r=Amanieu 
Expose `ucred::peer_cred` on QNX targets to enable dist builds

After following https://doc.rust-lang.org/rustc/platform-support/nto-qnx.html I attempted to run the following `x.py` command:

```bash
export build_env='
    CC_aarch64-unknown-nto-qnx710=qcc
    CFLAGS_aarch64-unknown-nto-qnx710=-Vgcc_ntoaarch64le_cxx
    CXX_aarch64-unknown-nto-qnx710=qcc
    AR_aarch64_unknown_nto_qnx710=ntoaarch64-ar
    CC_x86_64-pc-nto-qnx710=qcc
    CFLAGS_x86_64-pc-nto-qnx710=-Vgcc_ntox86_64_cxx
    CXX_x86_64-pc-nto-qnx710=qcc
    AR_x86_64_pc_nto_qnx710=ntox86_64-ar'
env $build_env ./x.py --stage 2 dist rust-std  --target aarch64-unknown-nto-qnx710,x86_64-pc-nto-qnx710,x86_64-unknown-linux-gnu
```

The result was the following error:

```
   Compiling object v0.32.2
   Compiling std_detect v0.1.5 (/home/ana/git/rust-lang/rust/library/stdarch/crates/std_detect)
   Compiling addr2line v0.21.0

   = note: `-D dead-code` implied by `-D warnings`
   = help: to override `-D warnings` add `#[allow(dead_code)]`

error: could not compile `std` (lib) due to 1 previous error
Build completed unsuccessfully in 0:06:25
```

I contacted `@flba-eb` and `@gh-tr` over email and we confirmed that `peer_cred` here should be flagged on `nto` targets. This should enable the clean `x.py --stage 2 dist rust-std` command on these platforms.
