    build: Generalize hack to ensure soup modules are a dependency of GIR
    
    We want to avoid meson version bumps, but this hack to ensure that GIR
    generation depends on the soup modules (since they will be pulled at
    runtime by g-ir-scanner during introspection) does not work across all
    meson versions.
    
    Use different hacks dependent on the meson version, so that the modules
    are a build-time dependency of the GIR target.
