fix(ansipa): Arch package/hostname fixes, safer seed_policystore delegation

- Use samba/openssh package names on Arch instead of Debian-style samba-client/openssh-server
- Skip AUR-only freeipa install when ipa-client-install already present; skip oddjob if not in official repos
- Guard seed_policystore delegate_to when ipa_server_host is undefined
- Make hostname detection and OS version parsing more robust
- Fix inverted DNS_UPDATE/CONFIGURE_SUDO enrollment flags
