Revert "Enable any address ports by default."

This reverts commit f04148c810aad2a0809dc8978650c55308381c47.

Reason for revert: Speculative revert. I suspect this is breaking a
downstream test (I'll reland if it is not the culprit).

Original change's description:
> Enable any address ports by default.
> 
> Ports not bound to any specific network interface are allocated by
> default. These any address ports are pruned after allocation,
> conditional on the allocation results of normal ports that are bound to
> the enumerated interfaces.
