Don't do that, it affects all following presubmit checks.

The work around I used in another PRESUBMIT.py file is to wrap that around a
try/finally. It's still loosy but it's better than this.

old_sys_path = sys.path
try:
  sys.path = [input_api.PresubmitLocalPath()] + sys.path
  import syntax_check_policy_template_json
  ...
finally:
  sys.path = old_sys_path

Done.
