patch 9.2.0426: tests: still some flaky screendump tests

patch 9.2.0426: tests: still some flaky screendump tests

Problem: tests: still some flaky screendump tests
(James McCoy)
Solution: Replace flaky VerifyScreenDump checks with assert_* assertions
for Test_visual_block_scroll and Test_scrolloffpad_with_folds,
and remove the now-unused dump files, mark those tests as
flaky (which happened previously for screendump tests
automatically) (Yasuhiro Matsumoto).
