LU-9311 tests: add sanity-pfl.sh test_13

This patch adds sanity-pfl.sh test_13 to verify the following fix:
https://review.whamcloud.com/#/c/26474/
test_13 uses 8 OSTs to make the LOVEA buffer bigger than the request
reply buffer, and writes data to the composite file to verify if the
layout write intent RPC resent by the client is reprocessed by
mdt_layout_change().

Test-parameters: trivial ostcount=8 testlist=sanity-pfl
