LU-17856 tests: ignore sanity stripe-count off-by-1

In some cases the MDS may not create all stripes on a file, if the
MDT-OST connection does not have precreated objects. This is OK,
so the tests should not fail the stripe-count check if trying to
create a fully-striped file and one of the stripes is missing.

parse_layout_param was modified to change the output value of
stripe count to be $OSTCOUNT if the stripe_count=$OSTCOUNT - 1.

Even if the stripe_count was meant to be $OSTCOUNT - 1 this
shouldn't fail any tests as both tested values will be modified.
