  ci: only push perf notes on master/release branches
  
  This patch fixes push_perf_notes logic in ci.sh to only push perf
  notes on master/release branches. We used to unconditionally push perf
  notes even in MRs, but the perf numbers in the wip branches wouldn't
  be used as baseline anyway, plus this is causing a space leak in the
  ghc-performance-notes repo. See #25317 for the perf notes repo size
  problem.

  ci: remove duplicate keys in .gitlab-ci.yml
  
  This patch removes accidentally duplicate keys in `.gitlab-ci.yml`.
  The YAML spec doesn't allow duplicate keys in the first place, and
  according to GitLab docs
  (https://docs.gitlab.com/ci/yaml/yaml_optimization/#anchors), the
  latest key overrides the earlier entries.

  libffiPath`/`Make libffiPath` builders, they are no longer needed
