[FIX] l10n_fr_account_vat_return: filter on VAT taxes for France

This commit adapts the code to the scenario where you have VAT taxes for
other countries (EU B2C over 10k€, Polynésie française, ...).
It "backports" the field country_id on account.tax which is introduced in
the account module in odoo v15.
