Fix libintl linkage and include directories (cmake transition fallout)

We checked for libintl in the top-level CMakeLists.txt but then never
used it for anything. This only ever worked on glibc where this all
is bundled in. Unfortunately Intl only becomes an importable target
in cmake >= 3.20 which is too new for us to rely on for now.

Python bindings are omitted here because we don't have any translated
messages in there. Whether we should is another topic.
