    vhost: enable log_shmfd protocol feature

    To claim that we support vhost-user live migration support:
    SET_LOG_BASE request will be send only when this feature flag
    is set.

    Besides this flag, we actually need another feature flag set
    to make vhost-user live migration work: VHOST_F_LOG_ALL.
    Which, however, has been enabled long time ago.
