Build: use standard infrastructure for translations

We now use standard framework generatedby "gettextize" utility.

It has two limitations which I do not consider sufficiently important
to invest into hand-made solution:

1. It can automatically gather strings only from files which have some
   file extension like .c or .py. Right now we do not have any
   translatable strings in Python files without extensions. Given that these
   files will be removed from source tree and replaced with entry points
   from setuptools I do not see a reason to invest into supporting this.

2. It does not automatically strip untranslated strings from po files.
   This is a manual step in mainteiner's in workflow anyway so I will
   add separate Makefile target for it later on.

This commit contains gettextize instrastructure + filled-in files
Makevars and POTFILES.in.
