LU-2902 test: ost stat parameters were not present

A few tests use roc_hit to sort out cache hits. These tests
were failing for a while because the lproc stats needed were not
present.

Use roc_hit_init with setstripe to correctly identify that basic
cache_access stats are working for each individual ost before
using roc_hit.

LU-3633 test: Sanity test 101d fails due to full OST

Sanity test 101d checks the available space on the file
system against the size of the file before writing, but
the file stripe is never checked or set. So, test 101d
has failed with enough space on the file system to write
the file, but the default stripe was 1 and there was not
enough space on that single OST for the file.

This patch sets the stripe of the file to -1 (all OSTs)
before writing to the file system.
