tests: use small conditional section for tic requirement in test-status-color.t
Better test coverage when curses not is available.
Check whether size of generaldelta revlog is not bigger than its
regular equivalent. Test would fail if generaldelta was naive
implementation of parentdelta: third manifest revision would be fully
inserted due to big distance from its paren revision (zero).
