Use CPDF_Dictionary::GetBooleanFor() for "ImageMask" key.

According to table 89 in ISO 3200-1:2008 spec, "ImageMask" is a boolean
key for Image Dictionary and its default value is false.

This CL uses CPDF_Dictionary::GetBooleanFor() instead of
CPDF_Dictionary::GetIntegerFor() to get the "ImageMask" value from the
Image Dictionary.
