Meson 0.49.0 depends on Ninja 1.5 or newer and that is available on
all supported distros.  On some of them the package is called `ninja`
and the rest uses `ninja-build`.

On CentOS/RHEL 7 the package is available only from EPEL.

On RHEL 8 the package is available from CodeReady Linux Builder
repository.

On CentOS 8 it should be available as well.

I'm not sure if we have EPEL repository in our CI VMs, but it should be
fairly easy to enable and in fact if there is someone using upstream
libvirt on CentOS/RHEL 7 they most likely have EPEL enabled as well.

Installing Meson using pip should be simple to implement.
