    ci: Limit depth of subprojects when cloning
    
    Use the depth= argument from Meson 0.52 to limit the clone depth of
    subprojects to 1. This should make the CI images a little smaller, and
    reduce the bandwidth required to build them (although that’s not so
    important because it only happens once every few months).
