Keep RTTI for Minetest IPO/LTO

Minetest using RTTI, so we cannot apply the flag here
if we want to start using IPO/LTO.

If we keep `-fno-rtti` here, compiler loses part of informations and
cannot do efficient optimizations.

The benefit of using RTTI on Irrlicht disappears with IPO/LTO on whole binary.
