freeipa.spec.in: -server subpackage should require samba-client-libs
    
    KDB driver extensively uses NDR parsing and marshalling code provided by
    Samba libraries. Since these libraries are internal to Samba, they often
    change structures without updating SONAME. Typical changes include
    adding new structures, so we should require samba-client-libs we were
    built against.
    
    There used to be %requires_eq macros in RPM but it was removed from
    Fedora some time ago. We need greater than or equal version of it, thus
    %ipa_requires_gt is defined in the spec file.
