update expected spec with capstone 3.0 (b53a59a)

Fix test so they pass with capstone tag 3.0 (https://github.com/aquynh/capstone/releases/tag/3.0), commit https://github.com/aquynh/capstone/commit/b53a59af53ffbd5dbe8dbcefba41a00cf4fc7469
It looks ok to me but I defer to your knowledge of the library whether that's really the expected spec and the changes are not needed somewhere else.
