fix: make bubblewrap conditionally installed for RedHat-based images (#1651)

* Initial plan

* fix: make bubblewrap conditionally installed on RedHat-based systems

bubblewrap is not available in UBI repositories, causing common-utils
installation to fail on UBI base images. This change checks package
availability before adding bubblewrap to the install list, following
the same pattern used for compat-openssl10 and redhat-lsb-core.

Also adds a test scenario for UBI 8 image.

* chore: bump common-utils version to 2.5.9
