Workaround for UBI9 container setup trouble (distributed-system-analy…

…sis#3554)

PBENCH-1277

This week the CI (and `runlocal`) builds have started failing because the
`ubi9` base image system can't install `rsyslog-mmjsonparse` anymore. It's
unclear exactly what changed, and specifying `ubi9.0.0` or `ubi9.1` isn't
reverting to the previous behavior, which I think means "something else"
I haven't discovered has changed environmentally.

For now, this PR just changes the default `BASE_IMAGE` to centos stream9,
which works fine, and will get the CI moving again.

We can revist this investigation later.
