glamor: Set AMDGPU_CREATE_PIXMAP_SCANOUT on DRI2 and shared pixmaps

Browse Source 
The scanout usage flag wasn't applied for DRI2 and shared pixmaps
in 0732f81a2c, resulting in GPU artifacts in some scenarios.

Fixes: 0732f81a2c ("glamor: Make pixmap scanout compatible if its
                      dimensions are")
Closes: https://gitlab.freedesktop.org/xorg/driver/xf86-video-amdgpu/-/issues/41
