Please expand `varlink::ListenConfig` to support socker permission

[Gris Ge]

In order to allowing everyone to talk to varlink socket file, I would like to set the socket file permission to 0666.

The possible ways I found is:

• Implement varlink::VarlinkService::handle by myself.
• Use service activator, still trying, not sure it works or not.

Can you expand ListenConfig so that varlink::listen() could set it?
