cmake: Don't enable useless warnings on GCC 

Using '-Wpedantic' on any GCC warnings enables a lot of annoying warnings that don't actually warn about anything. Some of the warnings seem to exist purely for maintaining a certain code style, and have no actual effect on the program itself. Since there is no way to selectively disable warnings like on MSVC, removing it is the easiest choice.
