[Stable-7.2.13 08/17] ci, docker: update CentOS and OpenSUSE Python to non-EOL versions

[Michael Tokarev]

From: Paolo Bonzini <pbonzini@redhat.com>

Python 3.6 is at end-of-life.  Update the libvirt-ci module to a
version that supports overrides for targets and package mappings;
this way, QEMU can use the newer versions provided by CentOS 8 (Python
3.8) and OpenSUSE 15.3 (Python 3.9).

    the ``libvirt-ci`` submodule to point to a commit that contains
    the ``mappings.yml`` update.
 
+For enterprise distros that default to old, end-of-life versions of the
+Python runtime, QEMU uses a separate set of mappings that work with more
+recent versions.  These can be found in ``tests/lcitool/mappings.yml``.
+Modifying this file should not be necessary unless the new pre-requisite
+is a Python library or tool.
