fix: exclude known noise from cache comparison and configs

- Hugo: exclude Linux-64bit legacy filename alias
- Hugo-extended: exclude Linux-64bit legacy filename alias
- Gitea: exclude -src- and -docs- tarballs
- Pathman: exclude armv8 legacy alias
- UUID v7: exclude exotic architectures (thumb, armeb, loong, gnux32, risc)
- comparecache: filter bare executables and docs tarballs as noise,
  apply noise filter to both live and Go sides
- legacy.go: add .tar.bz2 to legacyFormats

Match count: 69/106 (up from 58)
