[PATCH v2] clang-tools: Import os for broken pipe handling

[Ting-Han Hou]

The BrokenPipeError handler in run-clang-tools.py calls os.open() and
os.dup2() without importing os. If this handler is reached, it raises
NameError instead of redirecting stdout and exiting with status 1.

Import os so the handler can work as intended.
