    proxy: Remove use of libsoup-gnome
    
    It has been deprecated for a long while, and we were only using it for
    proxy support. However, now that we switched to using SoupSession rather
    than SoupSession{Sync,Async}, a default proxy resolver will be used, so
    we don't need to set it explicitly.
