Report Vesktop as a desktop client

Adds a patch to show Vesktop as a desktop client for users of Platformindicators. Vesktop aims to be a Discord desktop replacement with all the usual desktop features. Unlike the web(which Vesktop currently reports as) version that can run on different platforms, Vesktop is only for desktops.
