Clang-Tidy: Update builder to not run clang_tidy_warn.py

This CL has the builder not run clang_tidy_warn.py. This is because
clang_tidy_warn.py and all associated files have been migrated to
google3 at //googleclient/chrome/chromeos_toolchain/clang_tidy, and
are run by a daily borg job. Thus, we no longer need this builder to
run clang_tidy_warn.py.

BUG=None
TEST=None
