RenderThread: Make ~IFrameCallback() virtual

IFrameCallback has a pure virtual method, but its destructor was
non-virtual.  While CanvasContext, which inherits from
IFrameCallback, declares its own destructor virtual, this is not
sufficient when accessing via an IFrameCallback pointer.

We fix this by making the base destructor virtual.
