scripts/unocommands.py: Switch to python3

Files not explicitly opened in binary mode are text files and thus
expect a 'str' arg for their write() method.

Python 2 is nearing its EOL and e.g. Debian has already
removed the python2-based 'python-polib' package previously
used here from its testing distribution.

I checked that running the commands

    ./scripts/unocommands.py --update . ../libreoffice
    ./scripts/unocommands.py --translate . ../libreoffice/translations
    ./scripts/unocommands.py --check .

still yields the same results as previously.
