loader/dri3: Use client local back to front blit in copySubBuffer if available
The copySubBuffer functionality always attempted a server side blit from
back to fake front if a fake front was present, and we weren't displaying
on a remote GPU.
Now that we always have local blit capability on modern drivers, first
attempt a local blit, and only if that fails, try the server blit.
