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

• Listing fuzzy entries

• 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%
    

Comece pelos comandos do Makefile do repositório para todo, fuzzy e progress e, em seguida, compare a saída deles com os exemplos documentados de potodo nesta issue. Verifique como potodo seria invocado no Makefile e se a saída deve permanecer como o resultado de um comando ou ser armazenada como um arquivo. Está concluído quando os comandos selecionados de status da tradução fornecerem os resultados esperados no estilo do potodo.
