ci/cirrus: use vagrant from hashicorp repo

A version of vagrant available from the stock repos (2.2.19) is too old
and contains a bug that prevents downloading Fedora 38 image (see [1]).

Use packages from hashicorp repo, which currently has vagrant 2.3.4.
This resolves the problem of downloading the latest Fedora image.

Also, vagrant-libvirt plugin from Ubuntu repos is not working with
vagrant from hashicorp, so switch to using "vagrant plugin install".
The downside it, this takes extra 4 minutes or so in our CI, and I
am not sure how to cache it or speed it up.
