.gitlab-ci.d/cirrus: auto-generate variables with lcitool

The current Cirrus CI variables files were previously generated by using
lcitool. This change wires them up to the refresh script to make that
link explicit.

This changes the package list because libvirt-ci now knows about the
mapping for dtc on FreeBSD and macOS platforms.

The variables are also now emit in sorted order for stability across
runs.
