Fix T71259: Array Modifier Performance is slow

Was happening when object transform is animated.

Caused by overly aggressive dependency construction introduced a
while back in 9d4129eee649: we shouldn't add dependencies unless
we really need them.

This change removes unneeded transform dependency for cap objects
(since only their geometry is used), and also removes own transform
dependency if there is no offset object (which is the only case when
own transform is needed).
