    meson_options: Use libGLESv2.so.2 for COGL_DRIVER=gles2, not libGLESv2.so
    
    The former is present on any system that supports OpenGL|ES 2. The latter
    is just provided in developer packages. Since we access the library via
    `g_module_open` it's safe to just rely on `libGLESv2.so.2`.
