freeipa.spec.in: move ipa CLI utility to freeipa-client
    
    There is no notable package size cost, as all the libraries and
    packages are already in the freeipa-client package and
    freeipa-admintools only contained a short shim calling this code.
    
    Move /bin/ipa to freeipa-client, along with a man page and bash
    completion.
