Use CentOS 8 Stream tags for deps in master release

This is part of RDO transition to CentOS 8 Stream.

New cloud8s-openstack-wallaby-* tags have been created in CBS and
populated in [1]. Now it's time to switch update-deps.sh to use those
new tags to synchronize dependencies from CBS. Note that existing
cloud8-openstack-wallaby-* buildsys-tags will be removed from rdoinfo
and the dependencies updates must be done using
cloud8s-openstack-wallaby-testing.
