compositor: change rounding in weston_surface_to_buffer_rect()


Rounding both corners of the rectangle down can result in a 0
width/height rectangle before passing to weston_transformed_rect.

This showed up as missing damage in weston-simple-damage (the
bouncing ball would leave green trails when --use-viewport was
used)
