Switch fullstack/functional fips jobs to 9-stream

Master no longer support py3.6, so let's switch
these jobs to CentOS 9-stream which includes py3.9.

Also dbcounter[1] is not installable on CentOS 8-stream
and hence these jobs are currently broken.

Other fips jobs already switched with[2].

[2] https://review.opendev.org/c/openstack/neutron/+/833173

[Stable Only] The switch is to match defined runtimes per release
