fix: restore clean libwayland source from archive + force kded6 rebuild

- Restored wayland-libwayland-v1.24.0-patched.tar.gz from sources/
  to replace corrupted source with stray + characters from failed patch
- Force-rebuilt kf6-kded6 (deleted pkgar) so #ifdef Q_OS_REDOX guard
  is compiled in — kded6 now uses offscreen QPA on Redox
