Test 068 is the go-to test for freeze deadlock coverage;
unfortunately it only uses fsstress, which doesn't do any mmap
IO.
Using the existing fstest binary gets us a cheap mmap exerciser
as well.

I think it's fair to modify this test vs. making a new one -
it's never passed yet, and will only start passing in kernel 3.6,
so it shouldn't cause new test regressions to add mmap ops.
And I can verify that this finds mmap bugs; I had a backport
which messed up ext4's freeze vs. mmap handling, and this exposes
it. :)
