feat: collect scummvm and fbneo pinned revisions

RetroArch pins 23 ScummVM engine-data files and FBNeo's hiscore.dat at
revisions upstream history still holds; they are now collected. The
two profiles claim the revision their core is built from, so the pack
keeps serving the core its own files and the pins sit beside them.
