[PATCH] scripts: run-clang-tools: import os for broken pipe handling

[omer zalman]

The BrokenPipeError handler calls os.open() and os.dup2(), but the
module never imports os. A broken output pipe therefore raises
NameError while handling the original error. Import os so the
handler can redirect stdout and exit as intended.

The exact git-format-patch file is attached because Gmail's web
composer removes tabs from inline diffs.
