LU-3196 tests: a few fixes for > 10 OSTs.

1. Because the stripe index not necessarily follow OST index order,
even it specifies the index, so we should not check the layout by
OST inde order in sanity 27C.

2. In test 33c, it should print the OSTXXXX by %.4x instead of
%.4d.

3. In replay 44, timeout is under mds, instead of mdt.
