Delete all the GRR temp files in path.

    If path is a directory, look in the top level for filenames beginning with
    Client.tempfile_prefix, and delete them.

    If path is a regular file and starts with Client.tempfile_prefix delete it.

    Args:
      args: pathspec pointing to directory containing temp files to be
            deleted, or a single file to be deleted.
    Returns:
      deleted: array of filename strings that were deleted
    Raises:
      ErrorBadPath: if path doesn't exist or is not a regular file or directory
