Happens if gsutil was previously installed by a different user (typically if
someone originally installed in a shared file system location, using sudo).
Args:
tf: Opened TarFile.
dirs_to_remove: List of directories to remove.
old_cwd: Path to the working directory we should chdir back to if sudo is
needed. It's possible that we've chdir'd to a temp directory that's
been deleted, which can cause odd behavior (e.g. OSErrors when opening
the metrics subprocess). If this is not truthy, we won't attempt to
chdir back to this value.
Raises:
CommandException: if errors encountered.
