Rework FreeType related tests
Firstly, there is no fundamental difference between running the tests on freetype before and after 2.4.10, so we re-join the respective test cases. Secondly, there are some minor differences in the results depending on architecture, freetype versions and config options, so we cater to that by allowing small deviations from the expectations.
