Remove qstandardpaths_json.cpp
This implementation is unused. It was part of a platform that will unfortunately not see the light of day. Remove it since no one is maintaining it. Change-Id: I9e675225a32f227739c688608f937df66a14e9a4 Reviewed-by: David Faure (KDE) <faure@kde.org> Reviewed-by: Lars Knoll <lars.knoll@digia.com>bb10
