    xwayland: import DMA-BUFs with GBM_BO_USE_RENDERING only
    
    Drop GBM_BO_USE_SCANOUT from the GBM_BO_IMPORT_FD import, add
    GBM_BO_USE_RENDERING to the GBM_BO_IMPORT_FD_MODIFIER import.
    
    If the DMA-BUF cannot be scanned out, gbm_bo_import with
    GBM_BO_USE_SCANOUT will fail. However Xwayland doesn't need to scan-out
    the buffer and can work fine without scanout. Glamor only needs
    GBM_BO_USE_RENDERING.
