go.mod: update wireguard-go, taking control over iOS memory usage from our fork

Browse Source 
Our wireguard-go fork used different values from upstream for
package device's memory limits on iOS.

This was the last blocker to removing our fork.

These values are now vars rather than consts for iOS.

c27ff9b9f6

Adjust them on startup to our preferred values.
