Update a corpus test for fixing 2-point path filling.

https://pdfium-review.googlesource.com/c/pdfium/+/78191/ makes the
change that in fill mode, any sub path that draws a line between two
points should be rendered as a thin line even it doesn't form a closed
area. This CL updates the corpus test result for this change.
