[Titouan Christophe]

commit: https://git.buildroot.net/buildroot/commit/?id=0317555103111636f2068c7e7a633457eb27ed25
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2025.08.x

If the render gles2 is enabled then libgbm is required (see [1]).
Therefore, add the dependency to wlroots.
