LU-160 Reduce OST size requirement for test 155

The OST size requirements for sanity test 155 is reduced by running with
only a single-striped file on a particular OST, and only checking the
RAM on that OST's OSS node. Because it is no longer trying to create a
file larger than multiple OSS nodes' RAM while only striped over a
single OST, these tests should run at times when they previously would
not have.
