svga: fix FBO / viewport bugs

When drawing to a FBO, the viewport wasn't always set correctly.  It
was fine in the usual case of the viewport dims matching the surface
dims but broken otherwise.  In particular, this was happening because
the viewport scale is negative for FBO rendering.

The piglit fbo-viewport test exercises this.
