Avoid overriding system default DNS on macOS #3

Currenty, AG VPN overrides the system DNS settings on Mac. This is quite problematic. For instance, when you use it alongside AdGuard for Mac with DNS protection, it leads to random compatibility issues.

What's the reason for that? You can very well intercept DNS queries on the network level and re-route them to the DNS server of your choice.

As a simple solution, we could avoid overriding system DNS when it points to 127.0.0.1. At least it will fix compatibility issues with AG.
