These are basically the same as our test_badblock tests, except we
accept LFS_ERR_CORRUPT. This lets us test more checking modes that may
not enable recovery (ckreads, ckfetches, etc).
Well, in theory, at least. The lack of rollback protection gets in the
way of both ckreads and ckfetches, so we're currently only testing
ckprogs, which isn't much of an improvement. At least this gets the
scaffolding in place...
This also inverts the test_ck -> test_badblocks dependency. Now that
these both have exhaustive tests, we might as well limit test_badblocks
to simple erroring erases/progs and let test_ck check the ck checks.
