i965: Setup framebuffer texture in meta_draw_region.

With DRI2 we there is no screen region until a drawable is bound to
the context.  Set up the framebuffer texture in meta_draw_region instead
which should also handle the case where the draw region changes as a
result of resizing a redirected window or resizing the screen.
