This change fixes the buggy mouse movement in the SDL version of ROTT. The original implementation was manually calculating relative motion from absolute coordinates, which caused jumps and stopped working when hitting window edges. By switching to SDL2's SDL_SetRelativeMouseMode and using xrel/yrel directly, the mouse movement is now smooth and continuous, as expected for an FPS game.


PR created automatically by Jules for task 3269861212548935376 started by @h4mu

- Simplified `sdl_mouse_motion_filter` to use `xrel`/`yrel` directly.
- Switched to `SDL_SetRelativeMouseMode` for better FPS-style input.
- Confined changes to `rott/rt_in.c` as requested.

@h4mu, it would be a good idea to create another Windows binary with this greatly improved mouse support whenever you have a free moment.
