Rename textureinsgnode example to a more fitting name

It shows QQuickFramebufferObject. "Texture in QSGNode" is ambiguous
as it suggests another type of use case (where an existing texture is
imported and used with the QQ scene - without rendering to it). This
would conflict with upcoming future examples, so rename to fboitem, which
is what this example is about.

The link from examples.qdoc is already using the fitting title so that will
just work.
