minigbm: conditionally fallback to strip scanout use_flag
Only 2d virtgpu backend needs to fallback here because virtio primary
plane only allows DRM_FORMAT_XRGB8888.
Most our platforms cannot display YV12 (except msm), thus the fallback
is required for the converted DRM_FORMAT_YVU420_ANDROID. For virgl
backend, additionally append a BO_USE_LINEAR as a replacement for the
hack inside compute_virgl_bind_flags.
