Bug 12081: make tmpl_process3.pl delete ts temp files

This patch enable deletion of temp files used by
tmpl_process3.pl.
Just removed coments on existing code

To test:
1. Do a count of files on /tmp ( ls /tmp | wc -l )
2. Update preferred language
3. Count again, new files on /tmp
4. Apply the patch
5. Update again, check, no new files

NOTE: I watched what temp files were actually in /tmp to make
      sure other processes didn't magically increase/decrease
      the number.
          $ perl translate update {lang code}
      generated 10 temporary files for me (2x5 po files). After
      removing those ten files, and applying the patch, no
      other files were generated.
