    new: ci: Add jobs building RPM packages in mock

    Breakage in the RPM packaging sources is currently only discovered
    when a release is being packaged.  Build the packages in CI as well,
    from the "tarball-create" artifacts, using the packaging sources and
    the mock-driving Makefile from the public bind-rpms repository, and
    smoke-test them by installing them into a pristine chroot and running
    the installed binaries.

    Each job downloads several hundred megabytes from external services,
    so the jobs only run automatically in scheduled pipelines and have to
    be started by hand elsewhere.  They do not run in tag pipelines at
    all, so that a Copr outage cannot get in the way of a release.
