Update SerenityOS JBIG2 test files

https://github.com/SerenityOS/serenity/compare/d58a66717904a01a4...df40f5b88efb3f582

Not sure if there's a way to limit the comparison to just the
Tests/LibGfx/test-inputs/jbig2/json folder:

https://github.com/SerenityOS/serenity/commits/master/Tests/LibGfx/test-inputs/jbig2/json
(Changes after Jan 5 and before Feb 5.)

PDFium passes all these tests.
