Add a dirsrv requires to services that look up their names in LDAP

Some services aren't included in ipaplaform.knownservices
like smb and winbind. It is possible to discover the
service name using the same method used by ipactl, via roles.

If dirsrv isn't started then this will blow up spectacularly
so use requires as a guard against it.

Fixes: #301
