Fixing a regression (black screen) caused by a commit 92b58156e7 ("ui/gtk: set scanout-mode right before scheduling draw").
The commit 92b58156e7 was made with an assumption that the scanout mode needs to be set only if the guest scanout is a dmabuf but there are cases (e.g. virtio-gpu-virgl) where the scanout is still processed in a form of a texture but is not backed by dmabuf. So it is needed to put back the line that sets scanout mode in gd_egl_scanout_texture and gd_gl_area_scanout_texture.
