fad2876 ci: Always print low ccache hit rate notice (MarcoFalke)

Pull request description:

  Looks like the hit rate is low, even on test changes such as https://github.com/bitcoin/bitcoin/actions/runs/21476546461/job/61867393974#step:10:3349

  to make it easier to debug, unconditionally print the low hit rate notice
