textproc/py-prettytable: add python3 FLAVOR

Hi,

The following diff adds python3 flavor on textproc/py-prettytable.
It is a required dependency for www/weboob (using python3).

I added a LC_CTYPE=C.UTF-8 in TEST_ENV (when using python3), in order to
let the testsuite to pass all tests.

Without it, 1 test fails (prettytable_test.PrintJapanestTest).

Thanks.
