fallback to gbm_surface_create if gbm_surface_create_with_modifiers does not work (#270)

- implements #269 
- some drivers don't support `gbm_bo_create_with_modifiers` in that case `gbm_bo_create` is used now.
- the `GBM_BO_USE_*` flags are a bit restrictive right now, in the future we might be able to drop `GBM_BO_USE_LINEAR`.
