fix(patches): widen RcppParallel system-tbb scope to all oneTBB-2021 platforms (#137)

## What

Widen the RcppParallel `system-tbb` registry patch scope from `[alpine, ubuntu-2604]` to `[alpine, ubuntu, redhat-10]`.

## Why

#135 fixed the TBB cluster on alpine + ubuntu-2604 only. A per-image audit showed the problem is broader: RcppParallel's bundled Intel TBB build fails on **every** build image with a modern toolchain (alpine/musl, ubuntu jammy/noble/resolute g++ 11/13/15, redhat-10 GCC 14), and only redhat-8/9 (older toolchains + pre-oneTBB system TBB) tolerate the bundled build.

The system-TBB fix applies wherever the image ships **oneTBB 2021+** (has the `tbb::detail::r1` namespace rstan needs):

| platform | system TBB | in scope? |
|---|---|---|
| alpine (all) | oneTBB 2022 | ✅ |
| ubuntu 2204/2404/2604 | oneTBB 2021.5 / 2021.11 / 2022 | ✅ (via `ubuntu` family token) |
| redhat-10 | oneTBB 2021.11 | ✅ |
| redhat-8 | TBB 2018 (classic) | ❌ pre-oneTBB → bundled |
| redhat-9 | TBB 2020.3 (classic) | ❌ pre-oneTBB, bundled works → bundled |

## Requires

The matching build-env-images env (`TBB_INC`/`TBB_LIB`) extended to all ubuntu + el10: build-env-images #13. Ship together.

## Verified

RcppParallel + rstan build and link (no `symbol not found`) on alpine, redhat-10, ubuntu noble and ubuntu resolute; RcppParallel builds on ubuntu jammy.
