po: stop stripping non-translated strings from po files

We previously adopted a minimization technique for po files which
stripped source locations and non-translated msgids in order to save
space in the git repos and have saner commit diffs.

At this time it is not possible to integrate with weblate while having
non-translated msgids stripped, as it will immediately add them back
again.

By keeping all non-translated msgids, our .po files are about x2 the
size at 37 MB vs the original 18 MB. This is still way better than the
original po/ directory which was 109 MB. We're saving 38 MB by still
omitting source file locations, and another 34 MB are saved by the
dropping of all languages which are 100% untranslated.
