Install util-linux into the target container

The util-linug RPM is not installed automatically as a dependency
when:
  * upgrading 9 -> 10
  * or when dnf is configured to: install_weak_deps=False
    (affecting all upgrade paths)

Missing util-linux package leads to error due to missing `su` command
inside the container.
