[Libguestfs] Updated signing key for libguestfs-related packages

I've started to sign new release tarballs with an updated public key that uses only SHA512 hashes: https://download.libguestfs.org/rich@annexia.org-pubkey.txt The previous one that was used to sign packages had SHA1 hashes and was therefore judged to be insecure. It is still available here [actually as a GPG binary key ring, for reasons]: https://download.libguestfs.org/libguestfs.keyring Hopefully this all works, but as always with GPG stuff it's very obscure and could have gone wrong.
