Put pofiles under po/, use one folder for each translated file.

This is an improvement over 67f7c956239a7bc811a1d655d389666048e45fc3,
and a final step for #task-7c5cd2aa-6d92-0423-bfa7-81f2e8436586.

Now instead of trying to convince po4a and mdpo to work together, each
tools gets it own folder and a pofile for each language.  This means
that if I want to translate files FOO.md and a-dir/BAR.txt to pt and
fr, the directory structure of po/ will be:

  po/
    FOO.md/
      pt.po
      fr.po
    a-dir/
      BAR.txt/
        pt.po
        fr.po

The po/ folder mirrors the directory structure of the input files, also
nesting down directories.

This way mdpo can do extration and update on its own way, and po4a can
do extraction and update on its on way.

The downside is that some translations will be duplicated, because
they can appear on more than one file.
