[kvm-unit-tests GIT PULL 02/12] s390x: selftest: Add prefixes to fix report output

To make our TAP parser (and me) happy we don't want to have two reports
with exactly the same wording so I added in two new prefix pushes.

Also moving the code inside of the region of a prefix will give us
more data when a problem arises.
