Subject: [PATCH] [clang-tidy][run-clang-tidy] Fix minor shutdown noise

On my new machine, the script outputs some shutdown noise:
```
Ctrl-C detected, goodbye.
Traceback (most recent call last):
  File "/home/nvankempen/llvm-project/./clang-tools-extra/clang-tidy/tool/run-clang-tidy.py", line 626, in <module>
    asyncio.run(main())
  File "/usr/lib/python3.10/asyncio/runners.py", line 44, in run
    return loop.run_until_complete(main)
  File "/usr/lib/python3.10/asyncio/base_events.py", line 636, in run_until_complete
    self.run_forever()
  File "/usr/lib/python3.10/asyncio/base_events.py", line 603, in run_forever
    self._run_once()
  File "/usr/lib/python3.10/asyncio/base_events.py", line 1871, in _run_once
    event_list = self._selector.select(timeout)
  File "/usr/lib/python3.10/selectors.py", line 469, in select
    fd_event_list = self._selector.poll(timeout, max_ev)
KeyboardInterrupt
```

This fixes it.
