meta: enable vertex attributes in the context of the newly created array object
Otherwise, the function would enable generic vertex attributes 0
and 1 of the array object it does not own. This was causing crashes
in Euro Truck Simulator 2, since the incorrectly enabled generic
attribute 0 in the foreign context got precedence before vertex
position attribute at later time, leading to NULL pointer dereference.
