ci: lcitool: Maintain project package deps lists here

Each respective project that lcitool knows about and currently
maintains its list of package dependencies knows best what packages
they actually depend on. If a new dependency is currently needed, first
a change in lcitool is necessary before GitLab jobs and containers can
be updated. Provided a mapping already exists in lcitool (which can
quickly be added as an override via mappings.yml temporarily) we speed
up the whole CI update process by one step.
This patch adds all libvirt deps lists lcitool currently maintains for
libvirt.

Note that as with any overrides (since commit f199dd50) lcitool must be
invoked as '$ lcitool -d/--data-dir ci/lcitool ...'
