    texture-2d/wayland: destroy transient EGLImages
    
    When creating a texture from a wayland buffer we create an intermediate
    EGLImage that we then create a GL texture from, but we were never
    destroying that EGLImage. This patch ensures we destroy the image right
    after we've created the texture so we don't leak a reference to the
    underlying buffer.
