fix: Apply DMABUF workaround on all Linux systems (#789)

The previous implementation only applied the workaround on X11 sessions,
leaving Wayland users affected by WebkitGTK DMABUF crashes. This affects
various GPU configurations (at least Intel and NVIDIA) on both X11 and Wayland.

This change applies the workaround unconditionally on Linux, ensuring
the app doesn't crash on affected systems while having minimal performance
impact.
