containers: Avoid version specific installation of packages

Now that we have removed the `yum update` step, it doesn't make sense to
install the matching development packages based on the version already
present with the base container image. This is due to the fact that
their availability is not always guaranteed. Instead leave it up to DNF
to figure out if higher versions are available with the repositories.
