varde in the uhhm Arch registry

dist/arch/PKGBUILD packages the release tarballs: system and per-user
units, the per-user socket on for every session (as PipeWire's is; the
daemon starts only when an app connects), config and man pages. The
release workflow publishes it for x86_64 and aarch64 from klokka.
