exec-shared-gtt-* subtests use hardcoded values for object size and
softpin offset, based on 4kB page size assumption. That may result in
those subtests failing when run on future backing stores with possibly
larger minimum page sizes.
Replace hardcoded constants with values derived from minimum page size
of actual backing store the test is running on.
