Updated expected results in corpus test.

CL https://pdfium-review.googlesource.com/65752/ improves the process
of finding substitute font by removing the possible prefix in front
of the font's family name. This change will affect the AGG rendering
results and cause failures in corpus test. Need to update the failing
corpus testing results with the new AGG process.
