Change the looping logic in run-tests.sh

If a set of tests is provided, loop over the entire set the
requested number of times. Start and stop any requested tracing
across the set boundary.

 Versity ScoutFS Release Notes
 =============================
 
----
-v1.32
-\
-*June 2, 2026*
-
-Fix writing POSIX ACLs over NFS mounts that export the scoutfs
-filesystem.
-
-Add support for kernels in the RHEL 9.8 minor release.
-
-Reduce unneeded block allocation when data\_prealloc\_contig\_only was
-set to 0. This will help achieve more efficient data space usage when
-writing small files.
