As set out in bug #1933096 these bindings are dynamically built against
the version of libvirt present in the environment at build time.
As a result using a pre-built wheel can cause AttributeError's when the
bindings have previously been built elsewhere against an older version
of libvirt installed on the host. This is currently the case in CentOS 8
stream based CI jobs where we try to use 7.4.0 bindings that appear to
be built against libvirt <= 6.10 leading to bug #1933096.
This change seeks to avoid this by installing the bindings from packages
that will always be built against the correct corresponding version of
libvirt.
