[cleaner] Skip Size for directory output

[mahimabhosale]

sos clean always printed Size from os.stat() of the output path.
For a directory that is inode metadata (commonly 4KiB), not the
obfuscated data size.

Report Size only for packed archives, matching the
archive-vs-directory split in Policy.display_results.

Closes: #4396

As a suggestion, we could still report the cumulative directory size instead of not printing anything.

def get_directory_size(path):
    total_size = 0
    try:
        with os.scandir(path) as flist:
            for _f in flist:
                if _f.is_file(follow_symlinks=False):
                    total_size += _f.stat(follow_symlinks=False).st_size
                elif _f.is_dir(follow_symlinks=False):
                    total_size += get_directory_size(_f.path)
    except PermissionError:
        # ignore these instead of bailing out on size calculation
        pass
    return total_size

get_human_readable(get_directory_size(final_path))
