Temporary fixes rhel 9 distros

With [1] py39 constraints drop can't run fips jobs on
centos 9-stream or rocky9.
As a workaround can run with PYTHON3_VERSION: 3.11 in affected
jobs.
Until centos 10-stream support is ready[1] we also need
to install libvirt-python and uwsgi from source as uwsgi and
libvirt rpms are bundled with python3.
