M9.R.15q.4.5.c: fix M9.R.15q.4.5 stub sentinel paths

Validated each stub against the realized nix store output and
corrected the sentinel file paths that didn't match upstream:

  kdecoration2  - libKDecoration2.so -> libkdecorations3.so
                  (KDE Plasma 6 renamed)
  kwayland      - libKF6WaylandClient.so -> libKWaylandClient.so
  kglobalacceld - no .cmake config; use libexec/kglobalacceld
  hwdata        - pci.ids -> pnp.ids (Findhwdata.cmake probes pnp.ids)
  libqaccessibilityclient - no /lib/cmake/; use
                  libqaccessibilityclient-qt6.so
  kpipewire     - libKPipeWire.so -> libKPipeWireDmaBuf.so

Sentinel files are how the M9.R.14e nix resolver verifies a store
output landed correctly; wrong paths trigger 'nix realized outputs
without <declaredExecutablePath>'. Recipes compile cleanly.
