gallium: implement set_sample_mask() in all drivers

prevents segfault when state trackers try to set default mask.
Other option would be to make this required only for drivers
supporting multisampling, but this seems more clean.
Only dummy implementations (for normal drivers) provided (no driver
supports multisampling yet neither).
