[REM] test_pylint: remove PY2/PY3 restrictions
[REM] test_pylint: remove PY2/PY3 restrictions

Since Odoo no longer officially supports python 2, some of the
restrictions previously imposed by test_pylint are no longer necessary,
either because the usage of some builtin functions is legal (zip, map,
filter) or because the concerned function/module would already raise a
relevant error under python 3.
