[LTP] [PATCH v2] Add test for data integrity over NFS

It looks like block size (f_bsize member of struct statvfs) differs depending on
RAM. Testing on s390x VM:

* 1 GB => block size: 131072
* 2 GB => block size: 262144
* 4 GB => block size: 524288

This can cause timeouts depending on the machine setup.
How about changing TST_TIMEOUT=-1 ? I don't like unlimited setup, but in this
case I would keep it. Timeout is handled by fsplough.c anyway.
If you agree, I can change during merge.
