Many variants are never built anymore. Clean actions to just those still
shipped. But do not trigger named reload when named.run file is empty.
That is common on freeipa installation, where configuration changes
logging to put it elsewhere. named reload is disruptive because how
bind-dyndb-ldap behaves during reloads. Avoid unnecessary reloads with
visible service disruption.
Keep named-pkcs11 reload variant.
