fix _cairo_box_intersects_line_segment early rejection tests

As described by Tom, there seem to be problems with the early rejection tests
in _cairo_box_intersects_line_segment, or at least, I could see no logical
reason for the way they were written.

Fixing these to verify as expected that the box is either wholly to the left,
right, top, or bottom of the line segment, as done in this patch, fixes the
issue on these test cases in Firefox. We would appreciate if this patch could
get incorporated upstream.
