d3dretrace: Also recognise IDXGISwapChain1::Present as end-of-frame.

With commit f7e2fb30501fb8e5c84396013596e590fec50324 we create wrapper
objects for the most-specialised base class.  Which means that on a
reasonably up-to-date Windows 7 or Windows 8 we are bound to see
the IDXGISwapChain1::Present method, and never IDXGISwapChain::Present.
