http: Clean up usage of libsoup
Use libsoup rather than libsoup-gnome since libsoup-gnome is not required anymore. Bump the libsoup requirement to 2.42 to prevent a build failure with old libsoups (undefined references to soup_session_request_uri). Don't include individual libsoup headers as recommended by the libsoup documentation. https://bugzilla.gnome.org/show_bug.cgi?id=587890
