test: run the centos-9 test with an attached terminal

This commit changes the centos-9 test to run with `podman -t` so
that we have a test-case that uses the `terminal` progress. This
is prompted by:
a) we have no integration test currently that uses the terminal
   progress for the full build
b) a konflux failure/memory leak that showed because there the
   test is run with `-t`
