Fix the build

I tried running make on my M1 Mac and got this error:

make: *** [src/raylua_e.o] Error 1

So I fixed the types (by casting) in src/raylua_e.c and was able to compile and use raylua_e 🎉 . Looking further into the project, this seems the incorrect approach for the fix, the bindings might be wrong in tools/autocomplete/api/raylib_api.lua (line 3033, LoadFileDataCallback definition). Though I tried changing the types there and (even after make clean) the build still gives the same error.

This fixes the build for whoever needs it, but it's not the correct way to do it. If you can help me to fix it in the right place, I can change the Pull Request right away 🙂

I think the problem is due to raysan5/raylib@97ef819, we should instead change the parameter type of raylua_loadFileData
