tests: disable revlog compression in test-generaldelta.t (issue6867)
The revlog compression makes a lot of numbers unstable. Since checking revlog
compression is not the goal of this test, we disable the compression to get
stable numbers.
This should avoid wasting more time on this kind of changes in the future.
