Adopt `potodo` in Makefile

I found a tool named potodo that provides same functionalities with part of our current Makefile commands but has better format. We can consider adopting this tool in our Makefile (or even storing the output as a file and updating it whenever a PR is merged).

• Listing untranslated files

  • make todo

    > make todo           
    for file in *.po */*.po; do echo $(msgattrib --untranslated $file | grep ^msgid | sed 1d | wc -l ) $file; done | grep -v ^0 | sort -gr

• Get overall progress

  • make progress

    > make progress
    4.4%
    

  • potodo | tail -n2 | head -n1 | cut -c 10- | sed 's/[%].*$/%/g'

    > potodo | tail -n2 | head -n1 | cut -c 10- |  sed 's/[%].*$/%/g'
    4.31%
    

リポジトリの Makefile にある todo、fuzzy、progress 用のコマンドから始め、それらの出力をこの issue に記載されている potodo の例と比較します。Makefile で potodo をどのように呼び出すか、またその出力をコマンドの結果として残すべきか、ファイルとして保存すべきかを確認します。選択した翻訳ステータス用コマンドが、意図した potodo 形式の結果を提供すれば完了です。
