[clang-tools-extra] [Clang-tidy] Mark broken test as unsupported. (PR #191635)

[Baranov Victor via cfe-commits]

Could you please explain what exactly matchers right now and how it breaks? We renamed `main.cpp` to `cqc-main.cpp` so the original issue was "muted" temporary
>From build bots I've seen:
```cpp
error: PCH file '/opt/llvm-buildbot/home/solaris11-sparcv9/clang-solaris11-sparcv9/stage1/lib/Support/CMakeFiles/LLVMSupport.dir/cmake_pch.hxx.pch' uses an older format that is no longer supported [clang-diagnostic-error]
```
Which seems like a problem with PCH build.
