[Stable-8.0.3 05/54] ui/gtk: fix passing y0_top parameter to scanout

[Michael Tokarev]

From: Erico Nunes <ernunes@redhat.com>

The dmabuf->y0_top flag is passed to .dpy_gl_scanout_dmabuf(), however
in the gtk ui both implementations dropped it when doing the next
scanout_texture call.

Fixes flipped linux console using vhost-user-gpu with the gtk ui
display.
