swrast: fix incorrectly positioned putImage() in swrast driver
Some front buffer rendering was in the wrong position. This included
scissored clears, glDrawPixels and glCopyPixels. The problem was the
y coordinate passed to putImage() didn't match the y coordinate passed
to getImage().
We fix this by setting xrb->map_y to the inverted coordinate in
swrast_map_renderbuffer() which is used later by the putImage() call.
Also pass xrb->map_y to getImage() to be symmetric.
