chore: drop the liburing prerequisite, which was never used (#2560)
## Why

`IORingGroup` issues io_uring syscalls directly rather than linking `liburing`, so the package has
never been needed — but we ask operators to install it in the README, install it in CI, and check
for it in `build-tool`.

Verified against the **shipped** `IORingGroup` 1.0.9 assembly, not just the source:

| Symbol | Occurrences in `IORingGroup.dll` |
|---|---|
| `libc`, `libSystem.dylib`, `kernel32.dll`, `kernelbase.dll`, `ws2_32.dll` | present |
| `liburing` | **0** |
| `io_uring_queue_init` — liburing's entry point | **0** |
| `io_uring_setup` — the raw syscall | 1 |

If it linked liburing it would call `io_uring_queue_init` / `io_uring_submit`. It calls neither.

## What changes

Nine lines across three files, removing `liburing-dev` / `liburing-devel` from:

- `README.md` — both the dnf and apt prerequisite blocks
- `.github/workflows/build-test.yml` — both install steps
- `Projects/BuildTool/Prerequisites/NativeLibraryChecker.cs` — the cross-compile target text, the
  apt and dnf package lists, and the `ldconfig` fallback map

Nothing else is touched. `zstd` and the `-dev` packages are a separate discussion and a separate PR.

## Risk

None to the build. `liburing` was only ever installed, never linked or loaded — removing it cannot
change resolution behaviour. `build-tool` builds clean.

This was found while investigating why Linux requires `-dev` packages at all; that fix lives in the
binding packages (modernuo/LibDeflate.Bindings#4, modernuo/Argon2.Bindings#13) and lands separately
once those publish. This piece is independent and unblocked, hence its own PR.
