Remove even more numpy security duplications

With 3f887532 and b4c22280
we already moved numpy security duplications: this code already exists
in ERP5 (with erp5@a254bf50).
But we still missed some code parts: https://lab.nexedi.com/nexedi/wendelin/blob/b4c222803027a2d0d0fae793a4f16d4bea85f87d/product/Wendelin/__init__.py#L49-52
(perhaps because they looked different between erp5 and wendelin).

Furthermore with erp5@79fa584e the last
numpy parts which only existed in Wendelin were also migrated to ERP5,
which is why we can finally also remove this from Wendelin.

Now all numpy related RestrictedPython definitions can be found in
the ERP5 codebase and they are no longer distributed over both ERP5
and Wendelin.
