CCITTFaxStream: fix regression when EncodedByteAlign is true and EndOfLine is false

Fixes #5592.

I have manually checked the files from #5136 to be sure that they still render the same as before. This PR makes sure that PDFs where EncodedByteAlign is true and EndOfLine is false also enter the EOL check.
