Python 3.10, which is a requirement for Meson 1.12.0, was never packaged
for CentOS Stream 9 so update directly to 3.11.
CentOS 9 does not install meson from PyPI because configure will install
it from the bundled wheel; this way CI covers that path as well. This is
guaranteed because, when using a non-default Python, basically nothing
is installed.
The opensuse-leap-15.yml file was not in use anymore, so delete it
while touching tests/lcitool/targets/.
