CI: improve TX consistency

- txpush
   - don't try to push TX for the timezone list
   - xmllint --format the .ts files to avoid inconsistency between
     TX tool versions
 - txcheck
   - xmllint --format
   - hard-code the list of files, it's not worth the hassle
   - don't apply XML cleanups to POT files
   - strip linenumbers from POT files for diffing
