Jason A. Donenfeld c27ff9b9f6 device: allow reducing queue constants on iOS
Heavier network extensions might require the wireguard-go component to
use less ram, so let users of this reduce these as needed.

At some point we'll put this behind a configuration method of sorts, but
for now, just expose the consts as vars.
