CI: add cmake and g++ to Cirrus CI Linux container images

Tests requiring cmake and a C++ compiler have been recently
added. These tests also require a Meson version that was not yet
released at the time they were added and thus were skipped in most CI
jobs, thus the missing test dependencies were not noticed. Add them
now that the required Meson version has been released.
