Michal Privoznik 3b225256cd virshDomainNameCompleter: Prune accepted flags 
Only a small subset of VIR_CONNECT_LIST_DOMAINS_* flags are
actually used for this completer. Remove the unused ones. Note
that this is unrelated to other commands using
VIR_CONNECT_LIST_DOMAINS_* (i.e. cmdList) as this commit targets
the completer only and nothing else.
