config.sub: Recognize OpenHarmony OS

Add support for [OpenHarmony] targets.
The `ohos` targets are available [in `LLVM`] and
documented in the [Rust target documentation].

Known targets in Rust:

- aarch64-unknown-linux-ohos
- armv7-unknown-linux-ohos
- x86_64-unknown-linux-ohos

Known targets in Clang:
- arm-linux-ohos
- aarch64-linux-ohos
- x86_64-linux-ohos

There are also some additional targets available in clang,
e.g. `liteos-ohos`, but I don't know much about those
targets, so I'm leaving `liteos-ohos` out of scope for this
patch.

[OpenHarmony]: https://gitee.com/openharmony/docs/
[in `LLVM`]: https://github.com/llvm/llvm-project/blob/main/clang/lib/Driver/ToolChains/OHOS.cpp
[Rust target documentation]: https://doc.rust-lang.org/rustc/platform-support/openharmony.html

* config.sub ($os == ohos*): Recognize.
* doc/config.sub.1: Regenerate.
* testsuite/config-sub.data (aarch64-linux-ohos): New entry.
