Provide better handling about WireGuard for Windows

[maple3142]

Describe the bug If you enable WireGuard for Windows, your WSL can't correctly resolve dns without specifying it.

To Reproduce Steps to reproduce the behavior:

1. Install WireGuard from https://www.wireguard.com/install/
2. Connect to random working tunnel
3. In wsl, try nslookup google.com and nslookup google.com 8.8.8.8

Expected behavior Both works correctly.

Screenshots Failed: Success:

Additional context I know it can be solved (with steps I described below), but I think Pengwin can provide better compatibiliy about this.

Basic Troubleshooting Checklist

[x] I have searched Google for the error message. [x] I have checked official WSL troubleshooting documentation: https://docs.microsoft.com/en-us/windows/wsl/troubleshooting#confirm-wsl-is-enabled. [x] I have searched the official Microsoft WSL issues page: https://github.com/Microsoft/WSL/issues. [x] I have searched the Pengwin issues page: https://github.com/WhitewaterFoundry/Pengwin/issues. [ ] I have reset Pengwin: Settings->Apps->Apps & features->Pengwin->Advanced Options->Reset. [ ] I have disabled and re-enabled WSL in Windows Features. [ ] I have run Windows 10 updates and restarted.

What other troubleshooting have you attempted?

It can be solved by disabling generateResolvConf in /etc/wsl.conf and other weird tweaks. As disabling it isn't enough, there are unknown problem about /etc/resolv.conf being symbolic link.
