app-arch/xar-1.8-r4: revbump: fix musl, ppc-macos, version branding

- (attempt to) fix musl linking problem by pulling in fts-standalone
- fix ppc-macos/old Darwin compiles by disabling CommonCrypto usage in
  favour of libre/openssl, which we fully control wrt versioning etc.
- add Gentoo version to xar --version output
