Revert "cmocka: Drop as meson subproject"

This reverts commit 99eca0899b.

The environment provided by our Jenkins builder doesn't have cmocka.
It's not exactly known why it worked as a subproject. However, if it
allows us to enforce tests in the CI, we should revert now and drop
the subproject again once the environment is updated.
